Resumo
The process of plate perforation by sharp-nosed projectiles has attracted both experimental and theoretical attention during the last decades. However, due to the complexity of the process, there is no comprehensive model which can predict the values of ballistic limit velocities for a given projectile/target combination. In a recent paper we demonstrated that all the data for residual velocities as a function of impact velocity can be represented by a single normalized relation which is due to Recht and Ipson from the 1960’s. Thus, the only unknown physical parameter, which one has to determine experimentally, is the ballistic limit velocity (Vbl) for the set up at hand. In order to have a better insight to this issue we performed a large number of numerical simulations in which we varied projectile shapes, target materials and plate thicknesses.
