摘要

Flange earrings of strong anisotropic sheet metals in deep-drawingprocess are numerically analyzed by the elastic-plastic large deformation finite ele-ment formulation based on a discrete Kirchhoff triangle plate shell element model.A Barlat-Lian anisotropic yield function and a quasi-flow corner theory are used inthe present formulation. The numerical results are compared with the experimentalones of cylindrical cup drawing process. The focus of the present researches is on thenumerical analysis and the constraining scheme of the flange earring of circular sheetswith strong anisotropy in square cup drawing process.
