Abstract:The anisotropy of stamped sheet metal exerts evident effects on the formability. Barlat six-component yield function was introduced into the elastoplastic finite element formulation based on the principle of virtual velocity and the discrete Kirchhoff triangular element model. The flanging earing in cylindrical cup drawing process of circular sheet metal was numerically simulated. The influence of anisotropy on the forming process was studied.
Key words: anisotropy; Barlat six-component yield function; elastoplastic finite element; earing
