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.
根据成形极限图和规定最大回弹超差量来调整变形模式，找到优化的变形模式和拉弯轨迹。
Some foreign scholars developed the concept of Forming Limit Stress Diagram (FLSD) on the basis of FLD. FLSD is considered as strain path independent.
一些国外学者在板料成形极限图的基础上提出了板料应力成形极限图(FLSD)的概念，并认为板料应力成形极限图具有与路径无关的特点。
The improving processes are proposed based on the Forming Limit Diagram (FLD) analysis.
