Abstract: Foam sandwich tube is composed of two tubes and a lightweight foam core possessing various advantages, i.e., low density, excellent mitigation performance and energy absorption, etc. With the hope of enhancing the load ...

Abstract: The axial compressive deformed configurations of traditional and lightweight energy absorption thin-walled tubes are uncontrollable, while the introduction of internal and external induction grooves can control the deformed ...

Abstract: The failure behavior of geometrically asymmetric sandwich beams with a metal foam core is analytically and experimentally investigated. New initial failure modes of the asymmetric sandwich beams are observed under threepoint ...
