چکیده مقاله
Formability of automotive friction stir welded TWB tailor welded blank sheets was numerically investigated in biaxial stretching based on hemispherical dome stretch HDS test for four automotive sheets, aluminum alloy 6111 T4, 5083 H18, 5083 O and DP590 steel, with one or two different thicknesses Weld zone modeling approach effect and thickness ratio effect on formability was evaluated For numerical simulations, mechanical properties were utilized according to Chung et al 11 experiments To represent the mechanical properties, respectively, von Mises and Hill’48 quadratic yield functions was used for comparison of isotropic and anisotropic behavior of sheets along with the full isotropic hardening while the anisotropy of the weld zone was ignored for simplicity and compared with experimental results
