Mechanical modeling of Al-Mg alloy open-cell foams

Abstract

A finite element analysis was employed to simulate the deformation behavior of Al-Mg alloy foams of 92% porosity during compressive testing and the simulated results were compared with experimental ones. The crushable foam model developed in ABAQUS software for compressible foam materials could well reproduce the uniaxial compressive behavior in terms of stress-strain response and deformed geometry. In particular, the effect of friction between the dies and the foam specimen was discussed. ©2005 The Japan Institute of Metals.
