Innovative experimental setup for the investigation of material models with regard to strain hardening behavior

Abstract Sheet metal formed parts are often produced in multistage processes. The multi-directional deformations that occur this process pose a challenge for sufficiently accurate modeling of the material behavior. In paper, we present an experimental methodology and its potential serves as basis comprehensive validation models with respect to deformation. Therefore, results pre-strained DP600 specimens, which afterwards subjected by MUC-Test. MUC-Test has already been established validating under proportional loading. By using can be extended non-linearities load history. For purpose pre-strain sheet three conditions: uniaxial tension, plane strain equibiaxial tension. Thus, show is suitable representation histories useful models.
