A Multiparameter Damage Constitutive Model for Rock Based on Separation of Tension and Shear

By analysis of the microscopic damage mechanism of rock, a multiparameter elastoplastic damage constitutive model which considers damage mechanism of tension and shear is established. A revised general form of elastoplastic damage model containing damage internal variable of tensor form is derived b...
