Core crush criterion to determine the strength of sandwich composite structures subjected to compression after impact [PDF]

, 2008
In this study a core crush criterion is proposed to determine the residual strength of impacted sandwich structures. The core of the sandwich is made of a Nomex Honeycomb core and the faces are laminated and remain thin.
