Method & Evidence

AimTo determine the optimal design parameters for perforated ballistic armor panels to minimize weight while maintaining a specified level of ballistic protection against 7.62x54 armor-piercing rounds.

MethodExperimental and Simulation-based Optimization

ProcedureThe study involved validating simulation models (using LS-Dyna) against ballistic tests on flat armor plates of varying thicknesses. Material behavior models were refined based on high strain rate testing. Perforated plates were then simulated and tested, followed by an optimization process using Design of Experiments and Response Surface methodology to identify ideal parameters (hole diameter, spacing, plate thickness, air gap) for weight minimization.
