The Generalized Mohr-Coulomb Failure Criterion
Applied Sciences, 2023 With the construction of supertall buildings such as high earth dams, the linear envelope of the Mohr-Coulomb (M-C) failure criterion fitted to lower confined pressure would significantly underestimate the loading capacity of foundations, causing a huge ...

Range estimation of horizontal stress of deep rock based on Mohr-Coulomb criterion
Results in Physics, 2019 In-situ stress estimation is of great significance in deep coal mining. The vertical stress of the underground rock mass is generally estimated by the product of the upper cover average specific gravity and its depth, and it is difficult to estimate the ...

A non-stationary earthquake probability assessment with the Mohr–Coulomb failure criterion [PDF]
Natural Hazards and Earth System Sciences, 2015 From theory to experience, earthquake probability associated with an active fault should be gradually increasing with time since the last event. In this paper, a new non-stationary earthquake assessment motivated/derived from the Mohr–Coulomb failure ...

Stress-dependent instantaneous cohesion and friction angle for the Mohr–Coulomb criterion
International Journal of Mechanical SciencesThe strength criterion of rock is essential for stability control and safety design of geotechnical engineering constructions. Due to its widespread adoption, the Mohr–Coulomb (M-C) criterion is prominent among strength criteria. However, the M-C criterion is constrained by three significant limitations: it fails to capture the nonlinear strength ...

An Extension Strain Type Mohr–Coulomb Criterion [PDF]
Rock Mechanics and Rock Engineering, 2021 AbstractExtension fractures are typical for the deformation under low or no confining pressure. They can be explained by a phenomenological extension strain failure criterion. In the past, a simple empirical criterion for fracture initiation in brittle rock has been developed.

Application of the Modified Mohr–Coulomb Yield Criterion in Seismic Numerical Simulation of Tunnels
Shock and Vibration, 2021 To solve the classical problem that the Mohr–Coulomb yield criterion overestimates the tensile properties of geotechnical materials, a modified Mohr–Coulomb yield criterion that includes both maximum tensile stress theory and smooth processing was ...
