Mohr–Coulomb yield and plasticity. The Mohr–Coulomb yield surface is often used to model the plastic flow of geomaterials (and other cohesive-frictional materials). Many such materials show dilatational behavior under triaxial states of stress which the Mohr–Coulomb model does not include. See more Mohr–Coulomb theory is a mathematical model (see yield surface) describing the response of brittle materials such as concrete, or rubble piles, to shear stress as well as normal stress. Most of the classical engineering … See more The Mohr–Coulomb theory is named in honour of Charles-Augustin de Coulomb and Christian Otto Mohr. Coulomb's contribution was a 1773 essay entitled "Essai sur une … See more The Mohr–Coulomb failure (yield) surface is often expressed in Haigh–Westergaad coordinates. For example, the function Alternatively, in … See more The Mohr–Coulomb failure criterion represents the linear envelope that is obtained from a plot of the shear strength of a material versus the applied normal stress. This relation is expressed as $${\displaystyle \tau =\sigma ~\tan(\phi )+c}$$ See more • 3-D elasticity • Hoek–Brown failure criterion • Byerlee's law • Lateral earth pressure • von Mises stress See more WebAug 4, 2024 · Bai and Wierzbicki (2010) modified and extended Mohr–Coulomb (MC) fracture criterion to describe ductile fracture of isotropic crack-free solids in terms of equivalent plastic strain . The Mohr–Coulomb fracture criterion has been widely used in rock and soil mechanics [42,43].
