Modeling of reverse loading effects including workhardening stagnation and early re-plastification
Source abstract
Abstract
This paper deals with the Bauschinger effect in sheet metal forming simulation. The concept of a new material model is presented able to accurately handle the phenomena of early re-plastification, transient softening and workhardening stagnation at load reversal. Besides the standard data used for simulations based on isotropic hardening, the model requires only four additional, physically comprehensible material parameters. The model is verified by means of tension-compression tests and springback simulations for hat profiles for three typical high-strength steel alloys.
