WebThe Abaqus Mohr-Coulomb plasticity model uses the classical Mohr-Coulomb yield function, which includes isotropic cohesion hardening and softening. It also uses a smooth flow potential that has a … WebOct 16, 2014 · Several materials behave in such a manner, including metals, soils, rocks, and concrete, for example. These give rise to an elastic behavior up to a certain level of stress, the yield stress, at which plastic deformation starts to occur. The elastic-plastic behavior is path-dependent and the stress depends on the history of deformation.

WebApr 20, 2024 · The higher cohesion values when compared with the initial vane shear yield stress value (0.3 kPa) is due to the time-dependent behavior. If one considers the experimental vane shear yield value at 15 min (Fig. 6), a yield stress value around 0.8 kPa can be seen, which is closer to the cohesion value achieved from the direct shear test.
