This article is devoted to solving problems with known theoretical solutions in the Fidesys software package. Within the framework of the work, modeling of a biaxial shear test of the ground and simulating a draft of a flexible foundation was done. The solutions obtained were correlated with the solutions of such problems in the Plaxis software package. According to the results of the study, it can be concluded that the Fidesys software complex allows solving problems in the field of geomechanics. At the same time, it is not inferior to recognized solutions in terms of functionality.

The paper discusses the use of acoustic emission, stress-memory effect, and X-ray computed microtomography (μST) to detect the onset of destruction of specimens of concrete and basalt which are widely used in construction. It is shown that the most informative parameter is acoustic emission activity based on which the onset of the formation of a main crack can be identified. The geometry of the crack is determined using computed X-ray tomography.
