A COROTATIONAL CONSTITUTIVE MODEL FOR LARGE PLASTIC DE-FORMATION ANALYSIS OF HARDENING MATERIALS

In this paper, a corotational constitutive model for large plastic deformation of isotropic and kinematic hardening materials is introdeced. This model relates the back stress tensor with the logarithmic strain tensor, providing not only a non-oscillatory solution using jamann rate, but also the same results using Jaurnann or Zaremba corotational rates. In other words, the response of this model is independent of the choice of corotational rate.
