3. 3 Problem Description The cup drawing test simulation with circular punch and blank is one of the most popular tests to verify the planar anisotropic behavior through the prediction of the earing profile. In the cylindrical cup drawing test, the material undergoes compressive deformation in the flange area due to the circumferential contraction. Some stretching occurs also in the radial direction of a cup. This test was simulated for a 6111-T4 aluminum alloy sheet based on the one-point shell element and Barlat's yield function. Also, FLD prediction and drawbead modeling with nonlinear springs were investigated. Assuming isotropic hardening, the yield function coefficients are kept constant during the simulation.
