High velocity impact modelling of sandwich panels with aluminium foam core and aluminium sheet skins

Liu, Chengjun; Zhang , Y X; Qin, Qing Hua; Heslehurst, Rikard Benton

Description

A finite element model is developed in this paper to simulate the perforation of aluminium foam sandwich panels subjected to high velocity impact using the commercial finite element analysis software LS-DYNA. The aluminum foam core is governed by the material model of crushable foam materials, while both aluminium alloy face sheets are modeled with the simplified Johnson-Cook material model. A non-linear cohesive contact model is employed to simulate failure between adjacent layers, and an...[Show more]
