Fracture of Metal Foams: A Discrete Modelling Approach

2008
A discrete model based on two-dimensional Voronoi tessellation has been used to study damage and fracture in open-cell metal foams. The present study focuses on elastic-fracture behaviour of the foam. A competition mechanism among various damaging struts leading to damage localization and formation of a fracture band has been observed.
