Dissipation functions and yield conditions for geological materials with internal constraints
Abstract
General framework of modeling plasticity in geological materials with internalconstraints is discussed in this paper. A family of plastic dissipation functionsdevoted to soil and rock mechanics is proposed. Present paper is a generalizationof Drucker-Prager model and earlier author’s papers, which has dealtwith incompressible metals. The proposed functions are dependent on the threeinvariants of the plastic strain rate tensor and material parameters. In the spaceof principal plastic strain rates the curves of constant dissipation have three axesof symmetry in the deviatoric plane. Internal kinematical constraints in the materialare utilized. Using the potential constitutive law the constitutive relationfor material is derived. Obtained yield surfaces have a conical shape in the spectralstress space. The failure surfaces have three axes of symmetry in the deviatoricplane cross-sections. The deviatoric cross-section curves of the failure surface maychange from equilateral triangle through the circle and then to the equilateraltriangle oriented in the opposite way.
