Abstract
This article examines the mechanism of destruction of a heterogeneous system, experiments were carried out with the simplest form of loading with a short-term tensile (impact) of a heterogeneous body - a high modulus fiber in a relative plastic matrix. Based on the study conducted in a direct experiment, it was shown that in a heterogeneous material not only under static loading, which researchers have long and well known, but under dynamic loading the principle of joint deformation is realized. Therefore, high-modulus crystals (“inclusions”) even at a large distance from the center of the explosion can be damaged (microcracks can form in them) and at minor stresses in the crystal of the host rock as a whole.
