A thermal elastoplastic model of the surface residual stress of ceramics grinding

A theoretical model of the residual stress of ceramics grinding has been established applying thermal elastoplastic mechanics theory. While grinding, as the path of the grinding wheel moves along the workpiece surface, the distributing regulation of the residual stress can be simplified to a thermal elastoplastic mechanical issue, under the action of both the moving centralized force and the heat source. Calculation and evaluation of the surface residual stress using the current revised procedure of finite element analysis is successful. Compared with an X-ray diffraction experiment method, satisfactory precision is displayed.
