In the framework of the Leibenzon-Ishlinsky approach, the problem of the loss of stability of a pillar of a cylindrical mine working is solved. The pillar material was assumed with an initial anisotropy corresponding to the layered structure. A crite

To determine a priori the unknown structure of the Earth and the forecast of catastrophic events such as earthquakes, it is suggested to apply the formulation of the Cauchy problem when both the Cauchy stress vector and the displacement vector as a f

The study is carried out into the stability of edges of open pits with a stratified structure. The angle of the strata slope and the ultimate elastic compressive and shear strengths are assigned. The maximal allowable depth of an open pit is determin

The solution to the problem of improving the mechanical properties (including cyclic strength) of structural materials is largely dependent on our knowledge of the laws governing the development of microplastic deformations in them. The effect of hea
