Experimental and numerical analysis of the cup drawing test for orthotropic metal sheets

This paper describes experimental and numerical results concerning the deep -drawing test of a cylindrical cup. Numerical predictions obtained using th e anisotropic yield function proposed by Ferron and co-workers are discusse d and compared with results on IF steel and on tinplate steel. It is shown that the reliability of predicted strain distributions and earing profiles is closely related to an accurate description of anisotropic yield surfaces . (C) 2000 Elsevier Science B.V.
