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(xué)者在板料成形極限圖的基礎(chǔ)上提出了板料應(yīng)力成形極限圖（FLSD）的概念，并認(rèn)為板料應(yīng)力成形極限圖具有與路徑無關(guān)的特點(diǎn)。

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(guān)的應(yīng)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(jié)果表明：不同加載路徑下得到的成形極限應(yīng)力圖接近于一條曲線，即基于應(yīng)力的成形極限圖是與加載路徑無關(guān)的；
