A Generalized Spline Finite Strip for the Analysis of Plates

摘要

In this paper, the original spline finite strip, which is based upon the thin-plate theory, is modified and generalized in the sense that the formulation is based upon a third-order plate theory and is applicable to thin plates and shear-deformable plates (e.g. thick isotropic plates and laminated composite plates). To extend its application to nonlinear analysis, displacement formulation is employed with geometric nonlinearity and small initial imperfection taken into account. To demonstrate the performance of the present finite strip in the analysis of plates, a number of numerical examples are given.
