Mechanical behavior of mild steel up to rupture: characterization and validation

Résumé

In this work, the initial anisotropy and its evolution with strain, hardening and rupture of DC04 mild steel are characterized by using (i) a phenomenological constitutive model composed by the non-quadratic Yld2004-18p yield criterion combined with an isotropic hardening law and (ii) a macroscopic rupture criterion. For this purpose, an inverse methodology of material parameters identification is implemented and a numerical prediction of rupture is performed. The obtained results are validated in a cup deep-drawing benchmark.
