Abstract
A method of determining the dynamic yield strength of heterogeneous materials is proposed, based on comparisons of the processes of cavity formation in the reference and examined materials. A series of computations is performed for penetration of an elongated rod into homogeneous and heterogeneous massive targets. A nonmonotonic dependence of the penetration depth on the motion velocity is derived. The yield strength limit of a heterogeneous medium is obtained from the analysis of computation results in the coordinates of the specific kinetic energy of the rod and the work of stresses on plastic strains.
