...). Contact procedure Finite element method Viscoplasticity The interface between the tools and the part ðΩ_f, is assumed to follow a power friction law (Montmitonnet et al., 1988): (3) where τ is the friction shear stress, α and p...

... Contact procedure Finite element method Robustness Three‐dimensional In this paper, a general 3D contact procedure is presented. With respect to the existing literature on the subject, emphasis was put in this work on generality and robustness, since the procedure is intended for general...
