Viscoelastic plastic creep constitutive model based on energy conservation law and strain energy theory

Abstract On the basis of the law of conservation of energy, the three stages of rock creep are analyzed. The reasons for the difficulty in studying the accelerated creep stage of rocks using the traditional creep model are expounded. The triaxial creep deformation law and critical point parameter va...
