【Abstract】 Based on 3D progressive damage theory,a model of open-hole composite material plate in single-lap joint is developed,using the secondary development language of ANSYS software,to calculate the failure process under tensile load.Meanwhile,the failure modes of every layer are analyzed,and the initial failure load,final failure load and whole failure process of laminated plate are obtained.This provides a certain reference for the research on strengthening structure of composite plate with holes.更多还原
