A rate-independent non-associated constitutive model for finite element simulation of sheet metal forming

Mohsen Safaei UGent, Wim De Waele UGent and Shun-lai Zang (2012) Plasticity and its Current Applications, 18th International symposium, Proceedings. p.61-63
abstract
This paper presents a plane stress anisotropic constitutive model based on a non-associated flow rule (non-AFR) and a one-surface non-linear mixed isotropic-kinematic hardening law. A fully implicit stress update algorithm was used to implement the developed continuum formulation as a user material subroutine (UMAT) into the commercial finite element code ABAQUS. This model is capable of predicting the permanent softening of metals in addition to the Bauschinger effect and transient behavior.
