TL;DR: In this article, a composite front shield for a high speed train made of composite materials was considered, made of glass fiber epoxy face sheets with a polymeric foam core, and a series of static and dynamic impact tests were then run on the sandwich structure.

••
TL;DR: In this article, an experimental and computational study of the bending response of steel sandwich panels with corrugated cores in both transverse and longitudinal loading orientations has been performed, and it has been shown that when failure initiation is controlled by yielding, appreciable hardening follows the initial nonlinearity.

TL;DR: In this paper, the authors compared the deformation and elastic spring-back of the honeycomb sandwich panels and the monolithic plates of equivalent mass subjected to impact from foam projectiles, and found that the aluminum sandwich panels outperformed the air sandwich panels within an impulse range of 2.25 kNsm(-2) similar to 4.70kNsm(2).

TL;DR: In this paper, a method for fabricating metal foams based on the powder metallurgy process is presented, which allows for the production of complex-shaped foam parts, metal foam sandwich panels and foam filled hollow profiles.
Abstract: A method for fabricating metal foams based on the powder metallurgy process is presented. This foaming process allows for the production of complex-shaped foam parts, metal foam sandwich panels and foam filled hollow profiles. A range of alloys can be foamed using this method including aluminum, zinc, tin, lead and steel. The as-produced part has a closed-cell microstructure and a high fraction of porosity (typical range from 40–90% porosity). Selected mechanical properties of metal foams are evaluated, including the loading of foam samples with and without face skins and the axial crushing of tubular structures with foam reinforcement. Potential applications are discussed such as light-weight construction and energy absorption for both military and civilian uses.
