Metal plasticity

We are developing an elasto-viscoplastic constitutive model describing both the Bauschinger effect and the yield point phenomena (YPP). The numerical implementation of this model is based on the implicit method in order to conduct effective finite element simulations and provide accurate solutions. Predicting forming defects related to the YPP and optimizing the condition of the roller-leveling process can be realized with this model.
