| 摘 要： | 微分等达因法用于确定平面应力状态,可以不建立差分方程和分解次主应力而直接求解,在三维应力状态下,微分等达因法对应力模型具有非破坏性,通过把应力光学定律和弹性力学平衡微分方程联立采确定应力分量。

| Abstract: | BY the differential isodync method,the two-dime-nsional stress field may be determined directly without the equations of the shear difference method and the resolution of the second principle stress difference and sum. When the differential isodync method is applied to the solution of three-dimensional stress field,it is nondestructive. In order to determine the
components of the three-dimensional strcss, it needs the simultaneals of the three optic law and elasticity. |
