Impact damage of composite laminates with high-speed waterjet

Rain erosion may cause substantial damage to aircrafts during supersonic flight. Such event is investigated here via high-speed waterjet impact on composite laminates. An experimental setup is developed to produce waterjets with the speed up to 700m/s and a finite element model of the waterjet-composite impact event is established. The...

A blended continuum damage and fracture mechanics method for progressive damage analysis of composite structures using XFEM

Progressive damage analysis of composite structures remains problematic, holding back the full potential of these materials. Widely used continuum damage models feature a heuristical stiffness reduction to reflect damage, resulting in an unrealistic representation of damage patterns. To the end of a more realistic failure representation, this...
