Experimental and numerical study on honeycomb sandwich panels under bending and in-panel compression
TL;DR: In this paper, the effects of several key structural parameters on crashworthiness characteristics and collapse mechanism of honeycomb sandwich panels were explored through the experiments through the authors divulged that crashworthiness and collapse mode of sandwich structures were greatly influenced by the structural parameters under the TPB test.

Failure analysis of CFRP laminates subjected to compression after impact: FE simulation using discrete interface elements
TL;DR: In this article, a model for the numerical simulation of impact damage, permanent indentation and compression after impact (CAI) in CFRP laminates is presented, and the same model is used for the formation of damage developing during both low-velocity / low-energy impact tests and CAI tests.

Static and low-velocity impact behavior of sandwich beams with closed-cell aluminum-foam core in three-point bending
TL;DR: In this article, the response and failure of sandwich beams with aluminum-foam core are investigated, and the failure modes and crash processes of beams under impact loading are similar to those under quasi-static loading, but the force displacement history is very different.
