Micro-scale damage process in thermoplastic composites

Micro-scale damage process in thermoplastic composites

Details

​Micro-scale damage process in thermoplastic composites is studied by capturing the initiation and progression of principal damage modes (transverse crack, and its "migration" into delamination). The first attempt is to study the damage process in unbalanced-unsymmetrical cross-ply laminate at quasi-static rate. The next step is to capture the damage process at high speed.
