Empirical Mohr‐Coulomb Failure Criterion for Concrete Block‐Mortar Joints
Journal of Structural Engineering, 1994Modified 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.

Distortion Strain Energy–Based Mohr-Coulomb Criterion for Concrete Failure
Journal of Materials in Civil Engineering, 2017AbstractOn the basis of comprehensive analysis of experimental phenomenon and micro/mesomechanism, it is found that concrete failure is controlled by normal stress on failure plane and distortion s...

Establishment of a Dynamic Mohr–Coulomb Failure Criterion for Rocks
International Journal of Nonlinear Sciences and Numerical Simulation, 2012Abstract 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 ...

A modified mix design method for pervious concrete based on Mohr-Coulomb failure criterion
Construction and Building Materials, 2021Abstract Large porosity and connected porous structure enables pervious concrete to obtain water permeability, but significantly decreases its strength. It is still a critical challenge for the mix design of pervious concrete to well balance its permeability and strength.

Penetration of Targets Described by a Mohr-Coulomb Failure Criterion With a Tension Cutoff
Journal of Applied Mechanics, 1983A 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 ...

Mohr-Coulomb Failure Criterion Expressed in Terms of Stress Invariants
Journal of Applied Mechanics, 1998A polynomial expression for the Mohr-Coulomb criterion for failure of brittle or frictional materials in terms of stress invariants is derived. The form of the polynomial expression corresponds to the pyramidal shape of the failure surface in principal stress space. The pressure-sensitive character of the failure of a Mohr-Coulomb material is indicated

Evaluation of Aseismic Stability of Gangue Slope Based on Nonlinear Mohr-Coulomb Failure Criterion
Advanced Materials Research, 2011It is extremely important to establish hazard maps showing earthquake-induced displacements, safety factors and probabilities of failure. The combination of pseudo-static method and displacement-based method is commonly used to evaluate the stability of gangue slope.

Mechanics of Earth Fissures Using the Mohr-Coulomb Failure Criterion
Environmental and Engineering Geoscience, 2008Earth fissures are approximately vertical cracks in the ground. They are caused by natural events such as earthquakes or by human activities such as groundwater level decline due to pumping. The latter has become a major worldwide issue in areas where groundwater is pumped for domestic, agricultural, and industrial use.

The properties of anisotropic conical failure surfaces in relation to the Mohr–Coulomb criterion
International Journal for Numerical and Analytical Methods in Geomechanics, 1988AbstractAn 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.

Granular Matter, 2017
In this work, at first a new failure criterion for breakage of brittle particle systems is proposed, which combines the classical Mohr–Coulomb strength criterion with the probabilistic Weibull concept. This failure criterion is especially applicable to particle systems under compression load and accounts for the size-dependence of the material’s ...
