An Improved Nonlinear Dynamic Analysis of Flat Laminated Plates

Abstract

An improved finite element structural model has been developed for the dynamic analysis of flat laminated plates. This model is an extension of a model which has been developed and reported previously. The original model uses constant thickness quadrilateral elements to represent the shape of the plate with the elements stacked in thickness direction to account for the material properties of each layer. The new model allows for orthotropic elastic-visco-plastic material response and it uses finite difference equations for the time integration technique. Simplifying approximation allows for the use of large time increments in the finite difference equations for time integration.
