The results indicate that FEM can realize the complexstrain paths and different strain paths will affect the result of sheet metal forming greatly.
研究结果表明:有限元数值模拟可以实现复杂应变路径; 应变路径的不同对冲压成形的结果有很大影响。

Strain-based FLD is strongly affected by the strain path and has brought much inconvenience to the study of forming limit under complexstrain paths.
因极限应变构成的FLD受应变路径的影响很大,在研究复杂应变路径的成形极限问题时带来极大不便。

The thesis validates through actual experiments that FLSD is much more reliable and effective than the strain-based FLD in determining the multistage part formability under complexstrain paths.
