Abstract
Generally, commercial finite element method (FEM) software was used for sheet forming simulation. In this study, anisotropic yield function for aluminum alloy sheets was investigated by using commercial FEM software LS-DYNA V950. Cup deep drawing test and punch stretching test simulation have been carried out using 5000 series aluminum alloy (4.5%Mg, l. Ommt) sheet. There was a little difference between forming limit of cup test simulation by using various yield functions. The forming limit and the state of principle strain near the fracture measured by experiment (using scribed circle method) was in good agreement with the results calculated by using Barlat model (1989). Barlat model would be suitable to sheet forming simulation for aluminum alloy because of its yield locus similar to aluminum alloys.
