Abstract

In this paper, a modified and representative unit cell model was employed to study the crush behaviour of a closed cell metallic foam. The unit cell which captures the main geometrical features of the metallic foam considered was used to simulate crush behaviour in metallic foams. Both analytical using limit analysis and numerical using the finite element method were used to study the collapse behaviour of the cell. The analytical crushing stress of the foam was compared with FE results and was found to be in good agreement.
