Abstract
Composite materials are prone to a wide range of defects and damage which may significantly reduce their residual strength. Of the various types of defects possible, interply delaminations arising from in-service damage are probably the most insidious because of their effects on residual compressive strength and difficulties associated with their detection. In this study, a finite element analysis of the uniform expansion growth of a circular delamination in a compressed laminate is undertaken, and the results are compared with earlier analytical solutions.
