The primary objective is to compare numerical simulation results with experimental data, focusing on residual velocity during impact. Numerical simulations were conducted using ABAQUS software, employing the Johnson-Cook material model to replicate material behavior under high-strain-rate conditions. The simulations were designed to replicate the experimental setup reported by Gupta et al. The results demonstrate a strong correlation between numerical and experimental data, validating the computational approach. It was observed that mesh size significantly affects residual velocity, although its influence diminishes beyond a critical refinement level. This study provides valuable insights into the parameters influencing the ballistic performance of thin aluminum plates, contributing to the design and optimization of protective structures. © 2026 The Authors.
