Stury of Post-Failure Constitutive Relation Based on SMP Criterion
In this paper, based on SMP criteria, combination of strain softening of rock material mechanics theory, the after peak friction angle φ for the intermediate variables, the residual strain ε to express the after peak nonlinear elastic modulus E, and finally establish a unified non-linear constitutive model of the rock peak residual stress. Combination Xiao Guanzhuang Eastern Mine typical breakdown rock of diorite triaxial test , get stress-strain curves for different confining pressures by this model. It shows that peak constitutive relation of this study can simulate the experimental results, prove the rationality of the model.
