RISOn the Formulation of Strain-Space Plasticity With Multiple Loading Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An alternative formulation of plasticity is discussed in which strain rather than stress serves as the independent variable. The relationship of the formulation to traditional plasticity is ...
Discussion: “On the Nonequivalence of the Stress Space and Strain Space Formulations of Plasticity Theory” (Casey, J., and Naghdi, P. M., 1983, ASME J. Appl. Mech., 50, pp. 350–354)

On the Numerical Implementation of Elastoplastic Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form solution is given for the way stresses evolve during an elastoplastic time step under conditions of purely kinematic hardening or softening. When isotropic effects are included, ...
