Numerical Ricochet Model of a 7.62 mm Projectile Penetrating an Armor Steel Plate

Armored vehicles are designed to favor projectile ricochet and thus avoid perforation while providing a certain surface obliquity for the most probable threat direction. In the latest development not only new materials but also new design approaches are investigated using computer simulations. These simulations allow us to study quantitative dependencies of certain parameters which are difficult to determine experimentally, e.g. the influence of the surface roundness on the ricochet behavior of the projectile.
