Sažetak
The aim of this paper is to evaluate the effect of the radial constraints on the quasi-static and dynamic compressive crush performance of integral-skin closed-cell Al-alloy foam. The behaviour under different loading conditions (velocity and radial constraints) has been determined by an extensive experimental program. The results show a significant increase in the collapse stress of the integral-skin closed-cell aluminium foam under quasi-static loading when radial constraints are applied. The radial constraints induce a significant strain hardening to the foam, where the densification occurs at lower strains, consequently enhancing the energy absorption per unit volume of the deformed foam. The strain hardening is also sensitive to the foam density and is increasing with the density.
