Annotation

In the field of geomechanical calculations, it is proposed to use models with the so-called double hardening, based on the implementation of finite element approximation and analysis procedures. Their preference in comparison with the Coulomb-Mohr model representation is due to more accurate results of the coincidence of the final resulting mathematical modeling data compared with experimental experimental data. The use of the above components in the implementation of the algorithmic approach of this model representation allows us to legitimately interpret the picture of the emerging geomechanical situation: - this interpretation is associated with the emergence and formation of hardening zones based on isotropic compression, which is a consequence of the complex manifestation of processes in its contour from isotropic shear and compression with their simultaneous manifestations. The presence of these fragments makes it possible to determine quantitative values and trace the nature of the distribution of plastic deformations, as well as the size of this zone.
