Abstract:
Theory and experiments show that the general twin-shear stress criterion can represent the shear strength of soil and rock more accurately than the conventional Mohr-Coulomb criterion. However, there is no constitutive model based on the general twin-shear stress criterion in the existing large-scale finite element software. The smoothed function proposed by Gudehus-Argyr is essentially a corner model of the general twin-shear stress criterion for removing the sharp edges of the Mohr-Coulomb criterion. On the basis of studying the corner model, a plastic potential function was established, and the expressions of all flow vectors were deduced.
