Failure behavior analysis of the spherical-roof contoured core (Srcc) under quasi-static loading: a numerical study.

Sandwich structures have been increasingly used as advanced composite structures, and different core designs have been developed to improve the overall damage resistance characteristics of sandwich panels. It is challenging to decrease the impact influence under different loading conditions, which m...
