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

A damage accumulation finite element model of hybrid plain woven composite laminates is established within ANSYS software by using ANSYS parameter design language. The simulation of compressive behavior of hybrid plain woven composites laminates with a hole is carried out. It is found from the results that this model can simulate the whole damage and failure course of hybrid plain woven composites laminates with a hole and to predict laminate damage styles, damage development and compressive strength accurately Meanwhile, damage criteria and stiffness attenuation rules for this type of laminates are put forward and validated. The model gives visual results and is fit for engineering applications.
