Abstract:

Algorithms for integrating general classes of inelastic constitutive equations are described. The procedures reduce to the classical radial-return algorithm for J sub 2-flow theory and include extensions to isotropic elastic damage and Perzyna-type viscoplasticity. The methodology is applied to the cap model, which is useful for simulating the response of soils and concrete, and a uniquely simple and effective algorithm is developed which corrects shortcomings of previous implementations.
