A strength criterion for rocks

Mechanics of Materials, 2021
Abstract A simple strength criterion J 2 = α + β σ 3 is investigated to describe the ultimate stress capacity of rocks. This criterion takes the intermediate principal stress σ 2 into consideration. The nonlinear parabolic form on the meridian plane makes the present criterion is more suitable in rock mechanics than the ...

General Strength Criterion for Geomaterials

International Journal of Geomechanics, 2003
This note presents the results of a study on the variation of the strength of geomaterials. A general isotropic strength criterion is proposed which unifies the peak strength and critical state (or steady state) strength into one strength criterion. The proposed criterion describes the strength of a geomaterial in terms of its current stress state, its

Strength Criterion for Intact Rock

Indian Geotechnical Journal, 2016
Based on studies of the peak strength for soil by the authors, a simple strength criterion for intact rock is obtained in the general principal stress space. There are two material parameters in the equation. One is the uniaxial compression strength of the rock; the other describes the influence of stress level, and similar parameters are well studied ...

A criterion of strength for orthotropic materials

Fibre Science and Technology, 1975
The criterion of strength for anisotropic media proposed by Gol'denblat and Kopnov2 is adopted in this paper. The invariants for the strength function having orthotropic symmetry are used to formulate a criterion of strength for orthotropic materials.

Empirical Strength Criterion for Rock Masses

Journal of the Geotechnical Engineering Division, 1980
An empirical strength criterion for rocks and rock masses is proposed. The nonlinear criterion includes the uniaxial compressive strength of the intact rock material and introduces two dimensionless parameters, m and s. The parameter m varies with rock type, the angle of interblock or interparticle friction and the degree of block or particle interlock.

Peak shear strength criterion for mismatched rock joints: Revisiting JRC-JMC criterion

International Journal of Rock Mechanics and Mining Sciences, 2021
Abstract Rock joints with different matching conditions are widely existing in nature. The safety of engineering structure is significantly affected by the peak shear strength of mismatched rock joints; however, the available criteria do not work well for evaluating the peak shear strength of mismatched rock joints. In this study, the mismatched rock-
