Exact integration of constitutive equations in elasto-plasticity

Ristinmaa, Matti LU and Tryding, Johan LU (1993) In International Journal for Numerical Methods in Engineering 36(15). p.2525-2544
Abstract
A unified approach is presented for establishing exact integration of the constitutive equations in elastoplasticity, assuming the total strain-rate direction to be constant. This unified approach includes all previous exact integration procedures as special cases and, in addition, some new closed-form solutions are derived for combined kinematic and isotropic hardening. Special emphasis is laid on combined kinematic and isotropic hardening for von Mises' material and on isotropic hardening for Mohr-Coulomb and Tresca materials.
