Return mapping for nonsmooth and multiscale elastoplasticity

We present a semi-implicit return mapping algorithm for integrating generic nonsmooth elastoplastic models. The semi-implicit nature of the algorithm stems from “freezing” the plastic internal variables at their previous state, followed by implicitly integrating the stresses and plastic multiplier....
