... internal-variable theory for finite deformation of solids. This approach views inelastic deformation of a given material sample of the type considered under macroscopically homogeneous stress or strain and temperature as a sequence of constrained equilibrium states : the state of the material sample...

...Q. Yang; Y. R. Liu; J. Q. Bao In this paper, two subspaces of the state space of constrained equilibrium states for solids are proposed and addressed. One subspace, constrained affinity space, is conjugate-force space with fixed temperature and internal variable. It is revealed in this paper...

...Q. Yang; L. J. Xue; Y. R. Liu In this paper, the multiscale thermodynamic basis of the plastic potential theory is addressed within the irreversible thermodynamic framework with internal variables by Rice (1971, “Inelastic Constitutive Relations for Solids: An Internal Variable Theory and Its...
