| 摘 要： | 利用坐标变换法证明了一般三维塑性流动问题任意点应力状态 ,可以完全由三维最大剪应力迹线上的信息确定 ,进而利用共斜面法给出了三维塑性流动问题沿最大剪应力迹线正应力的变化规律。该规律为求解三维问题的应力应变分布 ,提供了重要的基本方程

| Abstract: | The information along 3D maximum shear stress tracing line is completely ascertained with the method of parameter transformation, then the changing rule of the normal stress along 3D maximum shear stress tracing line is discussed based on cobevel method. This law provides a valuable fundamental equation for solving the distributions of stress and strain of 3d problem. |
