| 摘 要： | 在变形过程中，变形区中各点处的应力状态差异很大，且同一点在变形过程中的不同时刻其应力状态也不相同，因而所引起的变形结果也各异。应力状态的变化过程可用屈服表面上的加载轨迹来描述，本文以镦粗为例对变形区中的不同点在屈服表面上的加载轨迹进行了研究。

| Abstract: | n plastic deformation processes, the stress states at various positions in the deformation zone are different from each other, and even the same point has a different stress state at a different moment. The change of stress states can be described with a loading path on the yield surface. In this paper, it is studied of the loading paths of the different points in the deformation zone. |
