Abstract

Abstract

Considering the compressibility of an aluminum-alloy foam and the unavailability of the classic Taylor model to it, a theoretical model used to analyze the Taylor impact experiment of the aluminum-alloy foam was proposed based on some assumptions. The Taylor impact experiment was performed to validate the proposed model and to explore the dynamic mechanical properties of the aluminum-alloy foam. The experimental results show that the strain-rate sensitivity of the studied aluminum-alloy foam is not strong.
