Numerical simulation of ductile fracture behavior for aluminum alloy sheet under cyclic plastic deformation

In this study, the FEM material model based on the crystal plasticity is introduced for the numerical simulation of deep drawing process of A5052 aluminum alloy sheet. For calculating the deformation and stress in a crystal of aluminum alloy sheet, Taylor's model is employed. To find the texture evolution, the crystallographic orientation is updated by computing the crystal lattice rotation. In order to verify the crystal plasticity-based FEM material model, the strain distribution and the draw-in amount are compared with experimental measurements. The crystal FEM strains agree well with measured strains. The comparison of draw-in amount shows less 1.96% discrepancy. Texture evolution depends on the initial texture.

Proof Strength

Tensile properties of 6061 aluminum alloy sheet were investigated by means of electric universal test machine, scanning electron microscopy ( SEM) etc．and compared with those parameters of 6010 aluminum alloy; By using machine performance parameters of 6061 aluminum alloy ,finite element software eta/DYNAFORM of Sheet Forming made the numerical simulation of Erichsen tester process of 6061 aluminum alloy sheet ,and the result of numerical simulation compared with actual Erichsen tester. The press forming performance of 6061 alloy sheet have been analyzed．The results show that compared with 6010 aluminum alloy, proof strength σs and tensile strength σb of 6061 aluminum alloy sheet exhibits worse,but even percentage elongation δ of 6061 alloy sheet exhibits similar; The value IE of numerical simulation exhibits similar with actual value IE. So 6061 aluminum alloy sheet have formability in a certain extent and apply in some fields of automobile instead of 6010 aluminum alloy.
