Abstract
The problems of numerical modeling of the behavior of fractured (non-cohesive) continuous media are related to the development of mining technologies (mainly, explosions on discharge), the study of landslide processes, as well as the phenomena established in seismically hazardous zones. The energy of deformation of unbound media is spent on overcoming internal friction and loosening. The description of irreversible deformations in non-cohesive media on the basis of physical models with constants included in them is possible if these constants are determined in laboratory or field experiments. In laboratory tests of specimens, it is not always possible to establish these constants directly, therefore, it is necessary to carry out additional calculations simulating test conditions.
