Abstract

The comparative analysis of the stress-strain state in the circuit and in the vicinity of a single generation of circular and arched curves of elastic and non-linear strain diagram types of rocks. Graphic dependences were obtained by  the finite element method, reflecting the nature of  the stress-strain state. The actual values of the tangential stress concentration factor on the circuit were obtained using non-linear functions.
