Abstract

Based on compression tests of closed-cell Al alloy foam measured, mchanical properties and energy absorption capability had been investigated. The compressive stress-strain curve of closed-cell Al foam consists of three distinct regions, i.e., the linear elasticity region, the plastic collapse region or brittle crushing region, and the densification region. Formula on energy absorption capability of closed-cell Al alloy foam was presented, which could provide theoretical support for its engineering application.
