摘要：

The isotropic yield behaviors of BCC and FCC metals under plane stress condition are simulated with the Taylor theory. The results are compared with a proposed yield function (Barlat-Lian yield function) in order to determine its parameter. Then the yield function with the correct parameter choice is incorporated with the M-K model to predict the forming limit of sheets, and to compare with a steel and an aluminum alloys, which gives good agreements with experiments.
