Abstrakt: In this paper, the model of elastic-plastic media in Drucker – Prager form was adapted for analysis of the stress state of the lithosphere. The Cratonic Jelly Sandwich model was used to define the cohesion and coefficient of internal friction dependences on depth. To test this adaptation, the mechanical behavior of deep geological structures was numerically analyzed. To create the computer structures of the researched region, the geological data of the "Shpat– 1983" profile was used. It is shown that plastic strain begins in the weak layers of the Earth's crust and upper mantle and progresses to the strong layers of the Earth's crust in the form of bands. [ABSTRACT FROM AUTHOR]
