This research deals with an analytical investigation of the problem of fracture under a moving contact, where the driving force for failure consists of both the contact stresses and the elastic stresses generated by thermal distortions. The project will consider both the isotropic (metals) and anisotropic materials (composites and non-metals). The result of this research will be important in many tribological applications, such as bearings, gears, brakes, and railway wheels.

本文对移动接触下的断裂问题进行了分析研究，其中破坏的驱动力既包括接触应力，也包括由热变形产生的弹性应力。该项目将考虑各向同性材料(金属)和各向异性材料(复合材料和非金属)。这项研究的结果将在许多摩擦学应用中具有重要意义，如轴承、齿轮、制动器和铁路车轮。
