Abstract

Abstract

Based on compression curves of spherical pores Al foam measured,compressive yield strength and energy absorption were investigated.The compressive stress-strain curve of cellular Al alloy consists of three distinct regions,i.e.,the linear elasticity region,the plastic collapse region or brittle crushing region,and the densification region.Spherical pores Al foam is a cellular metal material of high plastic performance,so energy absorption capability of it is bigger than that of spherical pores Al alloy foam.Compressive yield stress was in good agreement with Gibson-Ashby model’s expectation.The prediction for compressive yield stress is in agreement with the experimental results.
- spherical pore Al foam,
- compressive yield strength,
- energy absorption capability
