Bullet impact modeling on a steel plate
Abstract
Mathematical modeling is a powerful tool, especially when analyzing complex and potentially dangerous phenomena, such as bullet impacts. In this paper, the results of a finite element model of the impact of a long-distance, low speed 0.223 mm caliber bullet impacting a steel blank are presented. Several impact angles are simulated, showing bullet penetration and deformation larger than 50%. The results show impacts with penetrations or incrustations in the substrate or white plate and that cause deformations greater than 50%. The impacts of the projectile just touching the edge of the plate, allow to quantify the field of residual efforts on the target. These residual stresses are a numerical indication of the force of the impact.
