For the nonlinear fracture phenomena of rock,many numerical methods are carried out for study,but the numerical simulation methods for cracked rock are still being studied.Therefore,this paper combines the bilinear strain softening constitutive model with energy dissipation principle to establish damage constitutive equations;and through the strain energy density theory,energy failure criterion of mesoscopic element is established.When the strain energy of an element stored exceeds a fixed… CONTINUE READING
