A finite-element analysis of residual stress in stretch grinding

In this paper, effective models have been developed to simulate the mechani cs states of specimens during stretch and un-stretch grinding, by the therm al elastic-plastic finite-element method. The results of calculations show that stretch grinding can, under certain conditions, very effectively reduc e the residual tensile stress in the surface layer of the workpiece or even convert the residual tensile stress into residual compressive stress, Thro ugh analysis of the present results, the mechanism of the reduction of resi dual tensile stress by stretch grinding is revealed.
