An elastoplastic rotating cylinder with a rigid inclusion under plane strain condition is investigated. The analysis is based on infinitesimal strain theory, Tresca's yield condition, and its associated flow rule and perfectly plastic material behavior. Both loading and unloading are considered. It is established that secondary plastic flow may occur during unloading after a previous rotation, and the exact solutions for all stages of deformation are obtained. The results are illustrated by the distributions of the displacement, stress and plastic strain in a cylinder rotating at different speeds.

机械加载和卸载下具有刚性夹杂物的旋转圆柱的精确弹塑性分析

研究了在平面应变条件下具有刚性夹杂物的弹塑性旋转圆柱体。该分析基于最小应变理论，Tresca的屈服条件及其相关的流动规律和完美的塑性材料行为。装载和卸载都考虑在内。可以确定的是，在先前旋转之后的卸载过程中，可能会发生二次塑性流动，并获得了所有变形阶段的精确解。通过以不同速度旋转的气缸中的位移，应力和塑性应变的分布来说明结果。
