• Resumen

  • Many empirical and semi-empirical models that are widely used in impact dynamics employ the dependencies between the impact (initial) velocity and the depth of penetration (DOP). These dependencies are often obtained by statistical processing of experimental results and are not based on the theoretical models of penetration. In this study we develop an approach that allows using such phenomenological correlations for determining the dependencies of forces acting on a penetrator versus the instantaneous DOP and the instantaneous velocity. The developed approach can be also useful in other fields of mechanics.
