Simulation for laminate’s Delamination under out-of-Plane Impact with Modification of Interface Friction Effect

This paper proposes a modified method to predict composite laminate’s delamination under out-of-plane impact, which takes the interface friction effect as physical mechanism to explain the phenomena of interface strength’s enhancement under transverse load. Firstly, bilinear model is chosen to describe the relationship between traction and separation. Secondly, a macromodel of composite laminate under out-of-plane impact is given to show how the...
