Modeling of Anisotropy Influence on Thickness Distribution of Deep Drawing Sheet

In the current paper, numerical results of cylindrical cup drawing of aluminum-lithium sheets using the commercial software abaqus/explicit are presented. This software permits investigating physical models of real procedures putting singular emphasis on geometrical non-linearities produced by large deformations, material properties and complex conditions. Numerical simulation using finite element methods (fem) offers the ability of analysing the feasibility of a process, allowing the benefit of saving time and reducing costs by comparison with traditional methods. The 2090 t3 aluminum-lithium alloy was studied with the focus on the influencing plastic anisotropy that affect the final predicted part. The results illustrate that anisotropy influence the thickness variation, and a comparison between anisotropic and isotropic yield was discussed.
