WebAlthough the linear Mohr–Coulomb criterion is frequently applied to predict the failure of brittle materials such as cast iron, it can be used for ductile metals too. However, the criterion has some significant deficiencies which limit its predictive ability. In the present study, the underlying failure hypotheses of the linear Mohr–Coulomb criterion … WebThe developed failure criterion requires three independent load-bearing capabilities of the material, that is, tensile (T), compressive (C), and shear (S) strengths, as criterion calibrators...
WebSep 1, 2016 · The plastic shear dissipation energy always increases with increase of plastic shear strain. A new strength criterion is proposed for modeling the failure behavior of frozen soil. According to this criterion, a material point starts to fail when the total strain energy density reaches a critical value.
