补充资料：主应力
主应力
principal stress
zhuyingli主应力(prineipal stress)没有切应力作用的截面上的法向应力。经数学证明，金属塑性加工时于变形物体内某一点的应力状态可用下式所表示的二次曲面来确定: A“一‘X“十乞丁2+氏Z“+2场叉丫 +2殊yZ十2屯Z尤(1)式中A为任意常数，几、丐、么和rx.、，、几分别为作用在通过该点所引三个相互垂直坐标面上的正应力和切应力，X、Y、Z为此二次曲面上某点的坐标。当所取坐标轴的位置发生变化时，即用新的坐标来表示该曲面时，式中各项的系数将发生变化。这样，通过上述确定应力状态的点总可以引出这样三个相互垂直的平面(与坐标面平行)，在其上仅有正应力而无切应力。主应力符号的脚标分别用l、2、3表示，以分别代替正应力的脚标x、y、z。这样，所得到的三个主应力应为。1、。2、a:，分别作用在三个坐标面上。
