Numerical Analysis of Delamination Growth in Laminated Composites under Buckling Behavior

Abstract

In this paper, a delamination growth analysis on composite panel containing embedded delamination has been performed using a three-dimensional finite element model. The effects of the delamination on the local buckling load and delamination growth are studied by using Hashin’s 3D failure criteria via UMAT user’s subroutine of ABAQUS FE program. A new proposed model shows enhancement of the accuracy of the results which showed a good agreement with available experimental data.
