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 ...

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 ...

Slope stability analysis: Barodesy vs linear elastic – perfectly plastic models [PDF]
E3S Web of Conferences, 2019 The results of slope stability analysis are not unique. Different factors of safety are obtained investigating the same slope. The differences result from different constitutive models including different failure surfaces. In this contribution, different

A Three-Dimensional Elastoplastic Constitutive Model for Geomaterials
Applied Sciences, 2023 The Mohr-Coulomb (M-C) failure criterion has been a popular choice for geotechnical analysis because of its simplicity and ease of use. The fact that the M-C criterion disregards the intermediate principal stress’s impact is a significant drawback.

The Mohr–Coulomb criterion for intact rock strength and friction – a re-evaluation and consideration of failure under polyaxial stresses [PDF]
Solid Earth, 2016 Darley Dale and Pennant sandstones were tested under conditions of both axisymmetric shortening and extension normal to bedding. These are the two extremes of loading under polyaxial stress conditions.

A Macroscopic Strength Criterion for Isotropic Metals Based on the Concept of Fracture Plane
Metals, 2019 Although the linear Mohr−Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too.
