Three-Dimensional Finite Element Simulation of Residual Stress Field For Shot-Peening and Grinding

Abstract

The modeling and simulation of shot-peening and grinding process was carried out based on ABAQUS, in which the explicit dynamic finite element method was employed. This investigation studies the effect of grinding process on the workpiece residual stress field after shot peening. Furthermore, three-dimensional finite element model of multiple shot peening and grinding was built. The influence of different depth of grinding on the workpiece residual stress field after shot peening was analyzed. Meanwhile, finite element analysis results show that distribution of residual stress almost will not change after shot peening and grinding. But the overall residual stress moves down. Meanwhile grinding can increase residual compressive stress of surface and reduce the residual compressive and tensile stress of subsurface.
