Simulation of compressive failure of hybrid plain woven fabric laminate with a hole

An damage developing finite element model of hybrid plainwoven composite laminates was established by secondary development on ANSYSsoftware with ANSYS parameter design language. The simulation of compressivebehavior of hybrid plain woven composites laminates with a hole was carriedon. It can be found from the results that this model can be used to simulatethe whole damage and failure course of hybrid plain woven compositeslaminates with a hole and to predict laminate damage styles, damagedevelopment and compressive strength accurately. Meanwhile, damage criteriaand stiffness attenuation rules fit for this type of laminates were putforward and proved. The results by this model are visual and intuitionistic,so this model is fit for engineering application.
