Experiment/simulation correlation-based methodology for metallic ballistic protection solutions

Résumé

A methodology is developed based on the coupling of a finite element code with an optimisation module for the design of land vehicle armouring composed of lightweight aluminium alloy and high strength steel plate. Following an experiment/simulation correlation, a numerical model has been built and calibrated considering monolithic plates and then verified considering a bi-metal protection against tungsten carbide projectile mimicking the core of a 7.62x51 AP8 ammunition. In addition, a method is proposed to obtain the v res - v i curve for the full 7.62x51 AP8 bullet from the v res - v i curve obtained from the core only.
