Abstract Isotropic yield surfaces of both fcc and bcc metals have been simulated with theTBH model. Using the five--dimensional stress space proposed recently by Lequeu et al., theyield subsurface on any two of the three shear stresses can be considered approximately as in-scribed circles of their corresponding subsurface on π plane. Based on this concept, the HHHyield function has been transformed into the form where the parameters are uniquely deter-mined by two crystallographic factors: the mean Taylor factor in plane strain (M_p) and thecritical shear stress (τ_c) on slip systems.
