TL;DR: In this paper, the authors investigated the impact response and energy absorption properties of honeycomb sandwich panels subjected to a drop-weight impact under a spherical impactor and concluded that more than 80% of the impact energy is absorbed mostly by top face-sheet and honeycomb core.

TL;DR: In this article, a new type of multi-cell honeycomb (quadri-arc) was designed and a series of numerical studies on in-plane dynamic crushing behavior and energy absorption property under different impact loading.

TL;DR: In this article, an experimental and numerical investigation on surface deformation and energy absorption of aluminum honeycomb sandwich panels subjected to low-velocity impact is undertaken, where a high-speed camera system is employed to record the acceleration attenuation process of the impactor, and a projection profile system is introduced to measure the surface profiles of the panel and the depth of the ultimate indentation.

TL;DR: In this paper, the concept of hierarchy is incorporated into thin-walled circular tubes for a configuration with optimum energy absorption, and the behavior of these new classes of hierarchical tubes under axial crushing is investigated in terms of deformation modes, crushing forces and energy absorption.

TL;DR: In this paper, the out-of-plane crushing resistance of fractal-like honeycombs with self-similar hierarchy is investigated numerically and analytically, and the theoretical solutions are derived based on the Super Folding Element (SFE) theory to predict the mean crushing forces (MCFs) of the hierarchical honeycomb.
