  • 摘要：Micro-bolometer pixel is an essential element in the infrared focal plane array(IRFPA) of infrared detectors.Its response to infrared radiation is analyzed in this paper.The pixel structure is modeled as a composite laminate thin plate whose sides are measured with the thickness from 0.1-1 μm.Its middle ply is a ferroelectric thin film.Its top surface is covered with a gold or platinum infrared absorber,while the bottom surface is deposited with platinum or lanthanum-nickel.Meanwhile both surfaces are a pair of electrodes.The top surface receives infrared radiation pulses successively.For the very tiny micro bolometer pixel,it is assumed that the infrared radiation is uniformly distributed on the plate.Furthermore,as the ratio of the side length to the thickness of the plate is dramatically large,it is assumed that heat transfer only takes place across the thickness of the plate.The thermal-electric-mechanical coupling governing equations are solved in a form of Fourier series.Results of the displacement,temperature variation and electric output signals of the micro bolometer pixel structure under infrared radiation are obtained,analyzed and compared with experimental data.
  • 摘要：In the light of a growing need for fracture control of rapid crack propagation(RCP)ingas pipelines,a program PFRAC(Pipeline FRacture Analysis Code)has been developed to analysethc various events.In this paper,by using PFRAC for the simulation of axial crack propagation in gaspipelines,a number of dynamic analysis issues rclating to boundary effects for uncracked and crackedpipes are investigated.This indicates that the boundary conditions along the length of the pipe play animportant role for fracture analysis in the pipe.In contrast.the boundary condutions at thc ends of along pipeline have little effect on the dynamic fracture events.
  • 摘要：Applications of certain multi-parameter acceleration techniques used with the modified New-ton-Raphson (mN-R) methods to solve the nonlinear equations arising from rigid-plastic finite element analy-sis are investigated.New modified multi-parameter techniques,developed from Crisfield’s multi-parametermethods,are utilized to solve these nonlinear equations,The nnumerical performance of these techniques iscompared with the standard Newton-Raphson method (sN-R),Crisfield’s single parameter method (C1),Crisfield’s two parameter method (C2) and Crisfield’s three parameter method (C3).The new techniques donot involve additional residual force calculation and require little extra computational effort.In addition,theyare more robust and efficient than other existing acceleration techniques.
  • 摘要：By using the lattice model combined with finite element methods and statistical techniques,anumerical approach is developed to establish mechanical models of three-dimensional heterogeneous brittlematerials.A special numerical code is introduced,in which a lattice model and statistical approaches areused to simulate the initial heterogeneity of material properties.The size of displacement-load step is adap-tively determined so that only few elements would fail in each load step.When the tensile principal strain inan element exceeds the ultimate strain of this element,the element is considered broken and its Young’smodulus is set to be very low.Some important behaviors of heterogeneous brittle materials are indicated usingthis code.Load-displacement curves and figures of three-dimensional fracture patterns are also numericallyobtained,which are similar to those observed in laboratory tests.
  • 摘要：An energy-dissipation based viscoplastic consistency model is presented to describe the performance of concrete under dynamic loading.The development of plasticity is started with the thermodynamic hypotheses in order that the model may have a sound theoretical background.Independent hardening and softening and the rate dependence of concrete are described separately for tension and compression.A modified implicit backward Euler integration scheme is adopted for the numerical computation.Static and dynamic behavior of the material is illustrated with certain numerical examples at material point level and structural level,and compared with existing experimental data.Results validate the effectiveness of the model.
  • 摘要：A procedure for reanalysis of various structures subjected to various topological modifi-cations is presented.The procedure is based on the results of a single exact analysis and the factoriza-tion of the stiffness matrix of initial structures.It is suitable for the case of addition of joints,wherethe number of the degrees of freedom is increased.The method deals with the stiffness matrix of struc-tures directly,so it can be used with a general finite element system.It is shown that the proposed ap-proximation method is most effective in terms of accuracy,efficiency,and ease of implementation.
  • 摘要：The multi-layers feedforward neural network is used for inversion of material constants of flu-id-saturated porous media.The direct analysis of fluid-saturated porous media is carried out with the bound-ary element method.The dynamic displacement responses obtained from direct analysis for prescribed materi-al parameters constitute the sample sets training neural network.By virtue of the effective L-M training algo-rithm and the Tikhunov regularization method as well as the GCV method for an appropriate selection of regu-larization parameter,the inverse mapping from dynamic displacement responses to material constants is per-formed.Numerical examples demonstrate the validity of the neural network method.
  • 摘要：This paper proposes a new experimental method of quantitative plastic deformationanalysis by means of the thermoplastic effect. The incremental plastic strain distribution for a singleshear specimen was obtained by using this method.
  • 摘要：In this paper,a mathematical model for topology optimization of truss structures withconstraints of displacement and system reliability under multiple loading cases is constructed.In orderto avoid the difficulty of computing the structure’s system reliability,a solving approach is presented inwhich the failure probability of system is divided into the sum of all bars’ failure probability by meansof reliability distribution.In addition,by drawing into the reliability safety factor and the fundamen-tal relationship in structural mechanics,all probability constraints of displacement and stress are equiv-alently displayed as conventional form and linear function of the design variables.The optimizationproblem with multiple constraints is treated by the compact constraint tactics and is solved by the im-proved simplex method.The examples show that the approach proposed in this paper is feasible and ef-ficient.
  • 摘要：A new type of element which is suitable for solving the modes of the galloping long multi-spanbundle conductor structures is presented.The element is composed of all sub-conductor segments betweentwo spacers.Based on the linearized governing differential equations of the conductors,the mass matrix andstiffness matrix of the element in consideration of the constrained relations imposed on the conductors byspacers are derived.The dynamic characteristics of the galloping control devices can be directly added to theelement.The modes for an actual power line structure are computed by using the element formula and FEMprocedures,where seven cases of different galloping control device allocations are considered.Comparedwith the measured data,the method is shown to be reliable and effective.Analysis and discussions of thecomputational results are given.Some hints that are helpful to further investigation of galloping are also ob-tained.
  • 摘要：The transient thermal response of a thick orthotropic hollow cylinder with finite length is studied by a high order shell theory.The radial and axial displacements are assumed to have quadratic and cubic variations through the thickness,respectively.It is important that the radial stress is approximated by a cubic expansion satisfying the boundary conditions at the inner and outer surfaces,and the corresponding strain should be least-squares compatible with the strain derived from the strain-displacement relation.The equations of motion are derived from the integration of the equilibrium equations of stresses,which are solved by precise integration method(PIM).Numerical results are obtained,and compared with FE simulations and dynamic thermo-elasticity solutions,which indicates that the high order shell theory is capable of predicting the transient thermal response of an orthotropic(or isotropic) thick hollow cylinder efficiently,and for the detonation tube of actual pulse detonation engines(PDE) heated continuously,the thermal stresses will become too large to be neglected,which are not like those in the one time experiments with very short time.
  • 摘要：A nonparametric structural damage detection methodology based on neural networks method ispresented for health monitoring of structure-unknown systems.In this approach appropriate neural networksare trained by use of the modal test data from a ‘healthy’structure.The trained networks which are subse-quently fed with vibration measurements from the same structure in different stages have the capability of rec-ognizing the location and the content of structural damage and thereby can monitor the health of the structure.A modified back-propagation neural network is proposed to solve the two practical problems encountered bythe traditional back-propagation method,i.e.,slow learning progress and convergence to a false local mini-mum.Various training algorithms,types of the input layer and numbers of the nodes in the input layer areconsidered.Numerical example results from a 5-degree-of-freedom spring-mass structure and analyses on theexperimental data of an actual 5-storey-steel-frame demonstrate that neural-networks-based method is a robustprocedure and a practical tool for the detection of structural damage,and that the modified back-propagationalgorithm could improve the computational efficiency as well as the accuracy of detection.
  • 摘要：Three-dimensional edge cracks are analyzed using the Self-Similar Crack Expansion(SSCE) method with a boundary integral equation technique.The boundary integral equations for surfacecracks in a half space are presented based on a half space Green’s function (Mindlin,1936).By usingthe SSCE method,the stress intensity factors are determined by the crack-opening displacement over thecrack surface.In discrete boundary integral equations,the regular and singular integrals on the crack sur-face elements are evaluated by an analytical method,and the closed form expressions of the integrals aregiven for subsurface cracks and edge crakcs.This globally numerical and locally analytical method im-proves the solution accuracy and computational effort.Numerical results for edge cracks under tensileloading with various geometries,such as rectangular cracks,elliptical cracks,and semi-circular cracks,are presented using the SSCE method.Results for stress intensity factors of those surface breaking cracksare in good agreement with other numerical and analytical solutions.
  • 摘要：A meshless approach based on the moving least square method is developed for elasto-plasticity analysis, in which the incremental formulation is used. In this approach, the displacement shape functions are constructed by using the moving least square approximation, and the discrete governing equations for elasto-plastic material are constructed with the direct collocation method. The boundary conditions are also imposed by collocation. The method established is a truly meshless one, as it does not need any mesh, either for the purpose of interpolation of the solution variables, or for the purpose of construction of the discrete equations. It is simply formulated and very efficient, and no post-processing procedure is required to compute the derivatives of the unknown variables, since the solution from this method based on the moving least square approximation is already smooth enough. Numerical examples are given to verify the accuracy of the meshless method proposed for elasto-rdasticity analysis.
  • 摘要：The correction in the derivation of the Gurson yield criterion is reported.A prerequisite kine-matical condition ignored in Gurson’s paper is imposed,and a parameter （C1）,which was unreasonably setto zero,is restored.
  • 摘要：The mechanisms of interracial debonding of particle reinforced theological materials arestudied.Based on an energy criterion,a simple formula of local critical stress for interfacial debondingis derived and expressed in terms of the interfacial energy.The particle size effect on interface debond-ing can then be analyzed easily owing to the fact that critical stress is inversely proportional to thesquare root of particle radius.By taking PP/CaCO3 system as an example,the present energy criterionis compared with the mechanical debonding criterion,and it is found that under the condition that bondstrength is equal to matrix strength and particle radius not over 0.2μm,the mechanical debonding cri-terion can be automatically satisfied if the energy criterion is satisfied.A relation between critical timeand interface energy is calculated by using the energy criterion.The influences of the particle volumefraction and the parlicle size,the loading rate and the relaxation time of the matrix on the critical timeof interfacial debonding are also discussed.
  • 摘要：In this paper a new hierarchical boundary element method is introducedfor solving the problem of plate bending.Exact solutions of the governing equationsare used inside the domain together with independent deflections and rotations on theboundary.A generalized variational principle is employed to achieve the boundaryelement formulation.Further,the adaptive processes of the method are also discussed.By virtue of the error estimate technique proposed by Zienkiewicz et al.areasonable error indicator and adaptive scheme are suggested.Numerical examplesillustrate the high accuracy of the new elements and show the excellent efficiency ofthe adaptive computation described in this paper.
  • 摘要：Inclusion flaw is one of the worst flaws of powder metallurgy. The inclusion flaw plays an important role in the failure of high temperature turbine materials in aircraft components and automotive parts, especially fatigue failure. In this paper, an experimental investigation of fatigue microcrack propagation in the vicinal inclusion were carried out by the servo-hydraulic fatigue test system with scanning electron microscope (SEM). It has been found from the SEM images that the fatigue surface microcrack occurs in the matrix and inclusion. According to the SEM images, the characteristics of fatigue crack initiation and growth in vicinal inclusion for powder metallurgy alloys are analyzed in detail. The effect of the geometrical shape and material type of surface inclusions on the cracking is also discussed with the finite element method (FEM).
  • 摘要：The receptance approach to periodic structure theory is applied to studythe wave propagation and vibration power flow into a base-isolated multi-storeybuilding due to horizontal harmonic ground motion.Multi-storey buildings andlaminated rubber bearings have been modeled as periodic systems in this paper.Although the simplified model considered is quite simple,it is expected that it will bringforth the key differences between continuous and a single freedom systems.The resultsindicate that the isolation effectiveness depends on not only the number of storeys ofthe laminated rubber bearings but also the frequency characteristics of thesuperstructure.
  • 摘要：A boundary element method is presented for the coupled motion analysis of structuralvibration with small-amplitude fluid sloshing in two-dimensional space.The linearized Navier-Stokesequations are considered in frequency domain and transformed into boundary integral equations.Anappropriate fundamental solution for the Helmholtz equation with pure imaginary constant is found.The condition of zero-stress is imposed on the free surface,and non-slip condition of fluid particles isimposed on the walls of the container.For rigid motion models,the expressions for added mass andadded damping to the structural motion equations are obtained.Some typical numerical examples arepresented.
  • 摘要：A cantilever beam with Damping Material Applying Rubber Magnetic Powder (DRM) has been investigated. Two methods are selected to hold DRM to a vibrating steel beam, one is to attach DRM by the magnetic attractive force (called DRM beam) and the other by adhesive bonding (called AB-DRM beam). Different from the damping property of AB-DRM beam caused by shear deformation of damping material, the damping property of DRM beam is characterized by the sliding frictional loss together with the internal loss of damping material. The authors established a formulation to predict the damping characteristics of DRM beam, which was validated experimentally. It is found that rubber material loss factor β has a decisive in?uence on damping improvement of DRM beam versus AB-DRM beam. If β is smaller than the critical value around 0.8255, a valid range of vibratory amplitude always exists in which DRM beam can achieve better damping than AB-DRM beam; conversely, if β is bigger than the critical value, the valid range does not exist when slide occurs. Such results are used to determine the merits and limitations of DRM and develop design guidelines.
  • 摘要：By introducing the generalized quasi-symmetry of the infinitesimal transformation fortransformation group G,,this paper studies the conservation laws and symmetries of dynamical systemswith unilateral constraints in phase space.Noether’s theorem and Noether’s inverse theorem for me-chanical systems with unilateral constraints in phase space are obtained and two kinds of equivalentforms of generalized Killing equations which are used to determine the 8enerators of the infinitesimalgroup transformation are given.
  • 摘要：Some problems in the optimal topology design of structures with discrete variables arestudied in this paper.The problem of a model of discrete optimization is discussed and a neglected factthat discrete optimum design may be controlled by the discreteness of sizing variables and global con-straints is pointed out.A heuristic algorithm for solving discrete topology optimization problems oftrusses and frames is proposed.
  • 摘要：Active control of a flexible cantilever plate with multiple time delays is investigated using the discrete optimal control method. A controller with multiple time delays is presented. In this controller, time delay effect is incorporated in the mathematical model of the dynamic system throughout the control design and no approximations and assumptions are made in the controller derivation, so the system stability is easily guaranteed. Furthermore, this controller is available for both small time delays and large time delays. The feasibility and e?ciency of the proposed controller are verified through numerical simulations in the end of this paper.
  • 摘要：The semi-elliptical surface crack growth of structural components withuncertain material resistance under random loading is studied by using the stochasticaveraging principle.The FPK equation governing the transition probability densityfunction of crack lengths is derived.The analytical solution of the FPK equation forthe case of that the equations for the crack growth in the surface and depth directionsare uncoupled is obtained.The effects of the parameters of the stress process and of thematerial property on the behavior of semi-elliptical fatigue crack growth of thecomponents with deterministic resistance to crack growth in the stationary Gaussianstress process are examined.The comparison of the analytical result with digitalsimulation shows the effectiveness of the present method.
  • 摘要：A micromechanics method based on the High-Order-Theory developed by Aboudi et al. is used to predict the thermomechanical response of composites reinforced by shape memory alloy (SMA) fibers, and the non-uniform thermal distribution in composite arising from the process of heating or cooling is considered. The numerical development based on this model was coded to predict the thermomechanical response of shape memory alloy fiber/elastomer matrix composite subjected to thermal cycle loading. When the composite is heated, two heating ways, thermal gradients and heat source by passing an electric current through the SMA fibers are imposed on the composite respectively. Upon cooling, the first thermal boundary condition and the second thermal boundary condition are subjected to the composite respectively. A series of stress distributions and temperature distributions for different instants are calculated to reveal the interaction between the SMA material and matrix. It is useful to analyze and design the SMA actuator driven by heat source or the surface temperature.

  • 摘要：Combining Dual Reciprocity Method (DRM) with Hybrid Boundary Node Method (HBNM), the Dual Reciprocity Hybrid Boundary Node Method (DRHBNM) is developed for three-dimensional linear elasticity problems with body force. This method can be used to solve the elasticity problems with body force without domain integral, which is inevitable by HBNM. To demonstrate the versatility and the fast convergence of this method, some numerical examples of 3-D elasticity problems with body forces are examined. The computational results show that the present method is effective and can be widely applied in solving practical engineering problems.
  • 摘要：The problem of an anti-plane Griffith crack moving along the interface of dissimilarpiezoelectric materials is solved by using the integral transform technique.It is shown from the resultthat the intensity factors of anti-plane stress and electric displacement around the crack tip are depen-dent on the speed of the Griffith crack as well as the material coefficients.When the two piezoelectricmaterials are identical,the present result will be reduced to the result for the problem of an anti-planemoving Griffith crack in homogeneous piezoelectric materials.
