Abstract

Laminated composite plates are usually a part of complicated structures. Most of the cases these components may undergo delamination due to the transferring of various complicated loads. In this investigation the effect of extent of delamination on the vibration and buckling characteristics of laminated composite plate is studied by using FE method. Towards this, an eight-noded plate element has been used, by incorporating the effect of shear deformation. In this work two types of boundary conditions are used for calculating pre buckling in-plane stresses and buckling loads respectively. Matlab code has been developed to carry out various parameters like extent of delamination, ply orientation, plate thickness, width and position of load and boundary conditions.
