八面体应力
octahedral stress
bamianti yingli八面体应力(oetahedral Stress)作用在和三个主应力轴成等倾斜面上的应力。因这些等倾斜面构成具有四组平行平面的八面体(见图)，由此得名八面体应力。 八面体应力可分为八面体正应力和八面体切应力。 八面体正应力: a。一音(。+二+吼，用主应力表示时八面体正应力为: 。。一音(。1+aZ+a3，_) 八面体与八面体应力由此可见，八面体正应力等于应力张量第一不变量的三分之一。 八面体切应力::。一士粤x 一3 寸(ax一动2+(丐一动2+(几一几)“+6(魂十嵘+r!x)用主应力表示时八面体切应力为:一士音丫(。1一)2+(aZ一，2+(a3一，2用主切应力表示时八面体切应力为: 22。 r。=士于Vr爹:+r蛋3十r轰1 一3八面体切应力与偏应力张量的二次不变量的关系是: T。一衙 (王占学)
