摘要：

In this work a finite element analysis of geometrically nonlinear static and transiently dynamic behavior of laminated composite plates is presented. A higher order displacement field allowing both transverse shear and transverse normal strains is adopted through the analysis. The mass matrix, linear stiffness matrix, and nonlinear stiffness matrix for a typical discretized element are derived and presented. Several numerical examples are included, where comparisons among linear and nonlinear theories, the current displacement field and other displacement fields are made. Effects of laminate thickness, stacking sequences and stacking angles are also studied. One interesting result is that even for symmetric cross ply, linear theory can not provide accurate enough results.
