Many studies show that the improvement of the forming numerical prediction for rolled sheets is done through laws of increasingly complex behavior, in particular by combination of the isotropic and kinematic hardening (mixed hardening) to take account of the Baushinger effect. This present work classifies the steel grades compared to the Baushinger effect. For some forming cases, it shows also the influence of a mixed hardening law on this numerical prediction, in term of deformation, thinning, residual stresses, and punch force..
