A progressive failure analysis and finite element method are used to predict the failure and the response of laminated composites with hole, the accordingly object oriented postprocessor code is written by Visual Basic. Numerical simulation and experiments are done for T300/KH304 laminated composites with hole. The results show that the 2 D progressive damage model, analysis method and numerical simulation program can simulate the damage initiation, propagation and failure rules, response of displacement load very well. Some useful conclusions are given.
