| Abstract: | Focusing on carbon fiber composite laminates, this paper develops an integrated numerical analysis method that simulates the impact and compression after impact of composite laminates. Based on the Puck's failure criterion and the cohesive zone model, the intralayer damage and the interlaminar damage are described. The intralayer damage prediction and evolution are constructed using different damage reduction methods such as bilinear, functional, and direct reduction based on the fracture energy. A numerical simulation model for carbon fiber composite material impact and compression after impact was established. The effectiveness of the developed numerical analysis method was verified by carrying out the impact damage tests of different energy and the compression tests after impact. Results show that the bilinear damage evolution model of fracture energy has high accuracy in predicting the impact damage area and the compressive strength after impact for the carbon fiber composite laminates. |
