Component Mode Synthesis and Large Deflection Vibration of Complex Structures. Volume 2:Single-Mode Large Deflection Vibrations of BEAMS and Plates Using Finite Element Method. Final Report,Period Ending January 31, 1987,

摘要

A finite element method is presented for the large amplitude vibrations of complex structures that can be modelled with beam and rectangular plate elements subjected to harmonic excitation. Both inplane deformation and inertia are considered in the formulation. Derivation of the harmonic force and nonlinear stiffness matrices for a beam and a rectangular plate element are presented. Solution procedures and convergence characteristics of the finite element method are described. Nonlinear response to uniform and concentrated harmonic loadings and improved nonlinear free vibration results are presented for beams and rectangular plates of various boundary conditions.
