A compressive strength criterion for anisotropic rock materials [PDF]
Canadian Geotechnical Journal, 1988 This paper proposes a general compressive strength criterion for anisotropic rock materials under multiaxial states of stress. The proposed criterion is a generalization of the Von Mises' criterion for yielding of ductile metals, which has also been used previously as a strength criterion for brittle fracture in the spirit of both being limits of ...

Polyaxial strength criterion and closed-form solution for squeezing rock conditions
Journal of Rock Mechanics and Geotechnical Engineering, 2020 In this paper, a nonlinear strength criterion is proposed using the average of intermediate (σ2) and minor (σ3) principal stresses in place of σ3 in Ramamurthy (1994)'s strength criterion.

Method of strength analysis for doubly-curved stiffened orthotropic shells by various strength theories [PDF]
FME Transactions, 2023 The paper proposes a method of strength analysis for materials of thin-walled shell structures reinforced with stiffeners. The shells under consideration were made of orthotropic materials.

Empirical Shear Strength Criterion for Artificial Joint
IOP Conference Series: Earth and Environmental Science, 2019 Abstract An accurate understanding of shear strength in joints is critical to effective geotechnical engineering. The complete rock shear test continues to shear after shear strength reaches it speak value, resulting in the appearance of a softening stage and a residual stage.

A new strength criterion for structured soils
Journal of Rock Mechanics and Geotechnical Engineering, 2013 AbstractExisting strength criteria are mostly formulated to describe the mechanical properties of reconstituted soils. However, the engineering characteristics of structured soils are different from those of reconstituted soils in many aspects, especially in their strength properties.

Three-dimensional strength criterion for rocks: A review
Energy ReviewsDeep rocks are typically under a true-triaxial stress state. The strength of deep rock is thus dictated by both the direction and magnitude of principal stresses.

Strength criterion for rocks under compressive-tensile stresses and its application
Journal of Rock Mechanics and Geotechnical Engineering, 2015 Estimating in-situ stress with hydraulic borehole fracturing involves tensile strength of rock. Several strength criteria with three parameters result in tensile strengths with great differences, although they may describe the relation between strength ...
