Numerical simulation for plain woven composite laminate based on ANSYS software

Based on the software of ANSYS, an APDL code was programmed in which a progressive damage model was established to simulate the failure and the behavior of in-plane woven composite laminates numerically. In the model Hanshin criteria and Reddy stiffness attenuation methods which fit for uni-directional lamina were modified for in-plane fabrics. The experimental researches were carried out on G803/5224 laminates and laminates with a hole to verify this model. The simulating results with this model are coordinate with the test results very well. This method is relatively simple and intuitional when it is used to estimate the damage propagation and residual tensile strength. It would provide a numerical method for the analysis of the damage propagation and tensile failure of woven composite laminates, which is suitable for engineering application.
