Identification of Strain Hardening Phenomena in Sheet Metal at Large Plastic Strains KU Leuven
© 2014 The Authors. Published by Elsevier Ltd. A new experimental/numerical method to identify post-necking strain hardening phenomena in ductile sheet metal is presented. The identification of the post-necking strain hardening behaviour is based on the minimization of the external and the internal work in the necking zone during a tensile test. The proposed method takes the material state and the shape of the whole deforming tensile specimen ...
