Development of a Finite Element Method Program for the Analysis of Laminated Composite Plates Using First-Order Shear Deformation Theory

Abstract

A finite element computer program for determining the deflection and stresses in general laminated composite plates was developed. The program is based on first-order shear deformation theory of laminated plates with small deflections. The program includes the flexibility to impose general boundary conditions, has three different quadrilateral elements, and is able to analyze both static and dynamic plate problems. The program code tested favorably against results from other analytical methods and literature sources. The results from this program demonstrate the need to include shear deformation in the analysis of composite plates.
