By analyzing the real stress - strain curve with theory of plastic instability and using this testing method, another form of the forming limit diagram has been found.
在利用共稳理论对实际应力应变曲线进行分析的同时,得出了求作板材成形极限图的新方法。
Deformation mode is adjusted according to forming limit diagram (FLD) and maximum springback error, so the optimized one can be found, which in turn optimizes the stretch bending trajectory.
