Establishment of a Dynamic Mohr–Coulomb Failure Criterion for Rocks

International Journal of Nonlinear Sciences and Numerical Simulation, 2012
Abstract Static Mohr–Coulomb Failure Criterion for rocks has been used extensively in various rock engineering applications. In this model, the compressive strength, tensile strength, and shear strength are related. To investigate the applicability of the Mohr–Coulomb model to dynamic failures, we studied the correlation of the three ...

Uncertainty Analysis of Rock Strength Based on Mohr-Coulomb Criterion

2020
Due to uncertainties of the input parameters, such as the maximum principle stress, the minimum principle stress, the cohesion and the internal friction angle, the evaluation of the rock strength becomes the uncertainty problem. In such case, the uncertainty analysis method was proposed to deal with the uncertainty of the rock strength based on Mohr ...

Plasticity computations using the Mohr—Coulomb yield criterion

Engineering Computations, 1987
The paper describes the derivation and application of a range of numerical algorithms for implementing the Mohr—Coulomb yield criterion in a non-linear finite element computer program. Emphasis is placed on the difficulties associated with the corners of the yield surface.

Constitutive relations that imply a generalized Mohr-Coulomb criterion

Acta Mechanica, 1974
A class of constitutive equations are shown to imply a generalized Mohr-Coulomb criterion for impending flow. The stress is assumed to have an isotropic dependence upon a vector argument in equilibrium and this assumption leads to a constrained stress state which is of the type characterized by the Mohr-Coulomb criterion.

A generalized Mohr–Coulomb criterion implied by the revised Goodman–Cowin theory

Archive of Applied Mechanics, 2008
The author derives constitutive expressions in a revised Goodman-Cowin theory proposed by the author. In particular, the expression for Cauchy stress tensor is shown to imply a generalized Mohr-Coulomb criterion for the impending flow of granular matters. To this end, the concept of microcontinuum is employed: the effects of internal friction and other

The properties of anisotropic conical failure surfaces in relation to the Mohr–Coulomb criterion

International Journal for Numerical and Analytical Methods in Geomechanics, 1988
AbstractAn earlier publication1 considered the properties of circular conical failure surfaces whose axes coincide with the space diagonal in principal stress space. The present work uses a similar approach to analyse conical surfaces that are offset from the space diagonal.

Empirical Mohr‐Coulomb Failure Criterion for Concrete Block‐Mortar Joints

Journal of Structural Engineering, 1994
Modified values for the shear bond strength and coefficient of friction in a Mohr-Coulomb type of failure criterion for concrete block–mortar joints in masonry are calculated using finite-element analyses in which it is assumed that the state of stress in the joint is nonuniform.

The Mohr–Coulomb criterion from unit shear processes in metallic glass

Intermetallics, 2004
Abstract The experimental and simulation-based evidence for asymmetric plastic yielding of metallic glasses is reviewed, and discussed within the framework of the Mohr–Coulomb criterion. The weight of evidence is supportive of normal stress-dependent yielding, although it is difficult to ascribe the origin of this effect to a particular mechanism ...

A Simple Anisotropic Mohr-Coulomb Strength Criterion for Granular Soils

2018
Granular soils usually possess inherent fabric anisotropy due to natural deposition or compaction, leading to the dependence of peak shear strength on loading direction. In order to describe this strength anisotropy, a novel aniso-tropic strength variable Λ, which is determined by stress tensor and fabric orientation, is introduced to measure the ...
