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.

Relationships between LRI process parameters and impact and post-impact behaviour of stitched and unstitched NCF laminates [PDF]

, 2012
The general context of the development of out-of-autoclave processes in the aeronautics industry raises the question of the possible links between these new processes and impact behaviour. In this study, a Taguchi table was used in a design of experiment
