英语语法分析

An experiment with hemispheric punches reveals that the difference in their diameters and the specimen shape has some influence on FLD.

在用半球形凸模进行试验时发现，所用凸模直径和试件形状的不同对FLD有影响。

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。

Strain-based FLD is strongly affected by the strain path and has brought much inconvenience to the study of forming limit under complex strain 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。
