Lateral crushing and bending responses of CFRP square tube filled with aluminum honeycomb
TL;DR: In this article, the authors investigated the lateral planar crushing and bending responses of a carbon fiber reinforced plastic (CFRP) square tube filled with aluminum honeycomb, and the experimental results showed that energy absorbed (EA) and specific energy absorption (SEA) of the filled CFRP tubes could be significantly increased to 6.56 and 4 times, respectively, of those measured for the hollow tubes without fillings under lateral crushing.

Low-velocity impact behaviour of sandwich panels with homogeneous and stepwise graded foam cores
TL;DR: In this paper, the impact performance of sandwich panels with homogeneous and stepwise graded aluminium foam cores subjected to impact loadings was investigated via experimentation and finite element simulation in a drop-weight impact facility at four different velocities, the results of which were compared in terms of force displacement response, energy absorption and damage status.

Axial crush of metallic honeycombs
Enboa Wu,Wu-Shung Jiang +1 more
TL;DR: In this paper, experimental results for six types of honeycomb cellular structures under quasi-static and impact loads applied in the axial direction are reported, and an increase of up to 74% of the crush strength was observed when the specimens which were loaded dynamically were compared with those loaded under the quasistatic conditions and the increase was found to be proportional to the initial striking velocity of the projectile.
