Numerical study of the flange earing of deep-drawing sheets with stronger anisotropy. (English) Zbl 0985.74069

Summary: A Barlat-Lian anisotropy yield function is introduced into a quasi-flow corner theory of elastic-plastic finite deformation and into the elastic-plastic large deformation finite element formulation based on the principle of virtual velocity and on the discrete Kirchhoff triangle plate shell element. Then we present numerical simulations of the flange earing of deep-drawing process of circular sheets with stronger anisotropy, based on which we introduce schemes for controlling the flange earing.
