FIELD: test.
SUBSTANCE: invention relates to the field of controlled cracking in materials, in particular, in order to determine the properties of a given volume of material during the formation of cracks. Essence: carry out the determination of the target path of the crack in a given volume of material; and application to the specified material mechanical loads to control the propagation of cracks in the specified volume so that the crack propagates in the material essentially along the specified target fracture path, and the application to the specified volume of stabilizing load, the stabilizing load is formed in such a way as to avoid unstable crack propagation. System contains a test bench, configured to apply mechanical loads to the specified material and control the propagation of the crack in the bulk of the material so that the crack propagates through the material essentially along the target crack path, the test bench is also designed with the ability to apply a stabilizing load to the material in order to avoid unstable propagation of the specified crack.
EFFECT: technical result: ability to control the spread of the crack in the volume of the material, avoiding the unstable propagation of the crack.
