Abstarct: Earing is the difference in wall height of deep drawn cups. The most important thing which causes earing is difference in mechanical properties in different directions or anisotropy. Accurate prediction of this phenomenon and eliminating its undesired effects demands precise simulation of the in-plane anisotropic behavior of mextal sheets using advanced yield criteria. In this dissertation, the BBC2003 yield criterion, is used to predict earing in aluminum alloy AA3105 sheets. First, in order to determine the eight constants of BBC2003 yield criterion, an experimental-numerical method is developed in which uniaxial and plane strain tensile test results are employed. Nonlinear equations which govern these constants were derived and solved using steepest descent method. Then, uniaxial yield stresses and anisotropic coefficients are predicted using the yield function according to these constants and the results were investigated. The BBC2003 yield criterion is used in finite element analysis in ABAQUS software. To this end, VUMAT subroutine for describing elastic-plastic behavior of sheet mextal, is developed and verified. Then, using the developed subroutine, deep drawing of cylindrical cups of aluminum alloy AA3105 is simulated. The results of finite element analysis are compared with experimental ones. The difference in cup wall height and variation of thickness are the important parameters which are compared. The results show that BBC2003 predicts earing for aluminum alloy AA3105 precisely.
