Modeling of material failure in foam-based components

Abstract

The modeling of material failure in foam-filled beams was explored through numerical analyses with LS-DYNA. The study was based on previous physical tests on bending of square aluminum extrusions filled with aluminum foam. Recently implemented material models including fracture criteria for both extrusion and foam were used in the analyses. The objectives were to verify the numerical model, and to investigate the influence of different fracture criteria on the response.
