Mohr‐Coulomb Yield Criterion in Rock Plastic Mechanics

Chinese Journal of Geophysics, 2012
AbstractConventional Mohr‐Coulomb strength criterion only describing the relationship between normal stress and shear stress on the failure surface at the peak strength is used as a criterion to determine whether the beginning of rock's failure. This study extends the concept of the Mohr‐Coulomb strength criterion by suggesting that the Mohr‐Coulomb ...

Modified Mohr–Coulomb criterion for nonlinear strength characteristics of rocks

Fatigue and Fracture of Engineering Materials and Structures
AbstractThe classical Mohr–Coulomb criterion has an extremely wide range of applications in the field of engineering geology, while it cannot accurately characterize rock failure under high confining stresses. Therefore, a nonlinear modification is implemented based on the Mohr–Coulomb criterion for achieving wider usage in all stress environments. The

Qualitative Distinctions in the Solutions Based on the Plasticity Theories with the Mohr-Coulomb Yield Criterion

Journal of Applied Mechanics and Technical Physics, 2005
The following two models of the plasticity theory are considered: the model with Mohr--Coulomb yield criterion and the classical model of plasticity theory with a yield criterion independent of the mean stress. The authors study the deformation problem for a plastic layer enclosed between two rotating plates.

Modification of critical state models by Mohr–Coulomb criterion

Mechanics Research Communications, 2006
Abstract In order to combine the Mohr–Coulomb criterion and the critical state models for soils, a transformed stress tensor based on the Mohr–Coulomb criterion is proposed. The new stress tensor is determined by a transformation that makes the Mohr–Coulomb criterion become a cone having an axis as the space diagonal in transformed principal stress ...

Penetration of Targets Described by a Mohr-Coulomb Failure Criterion With a Tension Cutoff

Journal of Applied Mechanics, 1983
A model is developed to estimate the force on a conical-nosed penetrator for normal entry into geological targets that have linear hydrostats and fail according to a Mohr-Coulomb criterion with a tension cutoff. The model is applicable to targets with shear strength which either increases with pressure (dry rocks) or is constant (sea ice, concrete ...
