Abstract

The main focus of the experimental observation deals with the investigation of the plastic yielding of DC06 and DP600 under biaxial tension in comparison to an identified material model with an isotropic hardening behaviour. The isotropic hardening law describes the hardening behaviour of the material by application and approximation of the flow curve. Prevalent hardening laws are proposed by Swift (1952) or Hockett and Sherby (1975) and lead to an expansion of the yield surface in the stress space. By reasons of good accordance in an earlier survey the given materials are modeled by the yield criterion Yld2000-2d and the isotropic hardening law of Swift. In this case the yield loci at different experimental states of plastification are compared with the yield loci given from the isotropic expansion of the Yld2000-2d yield surface. Furthermore a possible approach for modelling the change of the yield criterion's shape in the stress space during plastification is shown. With respect to further investigations additional research work is needed including extended and complex hardening laws to describe the real material behaviour sufficiently. © (2013) Trans Tech Publications, Switzerland.
