Abstract

This study investigates the ballistic performance of aluminum alloy protective plates under projectile impact, focusing on thickness effects and projectile head geometry. By analyzing high strain rate responses, it reveals the sensitivity of deformation characteristics and failure mechanisms to structural parameters. To address the challenge in describing aluminum’s unique mechanical behavior during ballistic tests, the work systematically reviews applicable constitutive models and damage criteria. Furthermore, it evaluates predictive models for ballistic limits and energy absorption, providing theoretical support for understanding aluminum alloy behavior under complex impact conditions. The synthesized modeling approaches effectively resolve prediction difficulties in high-strain-rate scenarios with multiaxial stress states.
