Thermo-mechanical wear widely exists in various mechanical components. This paper improves the elastic finite element wear method to solve sliding wear problems with friction heat and elastoplastic behaviors. Especially, the thermo-mechanical wear method is illustrated in details, and the wear problems with full coupled thermal and plastic behaviors are numerically simulated for the first time based on the integration of power hardening law with Archard wear model. The local contact parameters are applied to solve the change of surface geometry and wear profiles based on the proposed wear model. After validation in ball-on-flat experiments, the comparing analysis indicate that friction heat and plasticity have great influence on wear evolution, the proposed method is more accurate than the elastic simulation method. The wear profiles, contact pressure, and temperature can be predicted effectively to help the designer further understand the wear process.

热机械磨损广泛存在于各种机械部件中。本文改进了弹性有限元磨损方法来解决具有摩擦热和弹塑性行为的滑动磨损问题。特别是对热-机械磨损方法进行了详细的阐述，首次基于功率硬化定律与Archard磨损模型的集成，对热塑性全耦合磨损问题进行了数值模拟。基于所提出的磨损模型，应用局部接触参数来解决表面几何形状和磨损轮廓的变化。经球对平实验验证，对比分析表明摩擦热和塑性对磨损演化有很大影响，该方法比弹性模拟方法更准确。磨损轮廓，
