forming limit stress diagram

基本解釋

Some foreign scholars developed the concept of Forming Limit Stress Diagram(FLSD) on the basis of FLD. FLSD is considered as strain path independent.
一些國外學者在板料成形極限圖的基礎上提出了板料應力成形極限圖（FLSD）的概念，并認為板料應力成形極限圖具有與路徑無關的特點。

Forming limit diagram is used for analyzing sheet forming in finite element analysis software have proposed forming limit stress diagram which is not relies on the loading path.
但它是依賴于加載路徑的，用它來分析多道次板成形是不合適的，于是人們提出了與加載路徑無關的應力成形極限圖。
The results show that the FLSDs obtained under the different loading paths are approximate to one curve, which means that the stress-based forming limit diagram is independent of strain paths.
研究結果表明：不同加載路徑下得到的成形極限應力圖接近于一條曲線，即基于應力的成形極限圖是與加載路徑無關的；
