Research Abstract |
In order to conduct accurate finite element calculations, new constitutive equations in the mezo and macro level have been studied for three years. The developed new equations have been developed to be able to describe both plastic anisotropy of the sheet metals and the yield conditions very accurately. The results of sheet metal deformation behaviors show good agreements with the corresponding experimental data. It is also confirmed the constitutive equations can deal with the non-proportional cyclic loading history. As results of discussion with some finite element venders, these constitutive equation have been determined to introduce into some commercial finite element codes.
