Year: 2025

Type: article

Abstract: This study investigates the dynamic response characteristics of aluminum foam materials under low to medium-high velocity impact loading, elucidating their deformation mechanisms and energy absorption capabilities through an integrated experimental and numerical simulation approach. The multi-stage deformation behavior of aluminum foam was investigated through the Taylor impact test, which demonstrated that impact velocity significantly affects its stiffness and energy absorption capability. The accuracy of stress distribution and mechanical properties during the impact process is validated, and the deformation behavior under medium- and high-speed impact conditions is clearly revealed. Through integrated macroscopic and microscopic analyses, the dynamic response characteristics of aluminum foam under various impact loads are systematically investigated, elucidating the mechanisms of internal pore collapse and dynamic compressive behavior, thereby providing robust theoretical support for the optimized design of aluminum foam in cushioning and protective applications.
