title: DEVELOPMENT OF CALCULATION METHOD FOR TENSILE STRENGTH OF ROCK SAMPLES UNDER COMPRESSION
abstract: The paper describes a procedure for improving the approach to determining the ultimate strength of rock samples, the basic method is L. Prandtl’s method. In earlier works of the authors of this paper, the L. Prandtl’s method was improved in relation to rocks, using a general algebraic equation for calculating horizontal normal stresses depending on the vertical component and mechanical characteristics of the rock. Here, the authors reject the assumption that the tangent contact stresses resultin
