Evolution of Residual Stress During Turning and ...
1982-1-1 In cylindrical grinding. the normal surface residual stresses (~11 and 022) are tensile in the direction of lay and compressive in the perpendicular direction. These also change with depth. However, only the shear stress 0 3 exists in this case ; 8~12 disappears since the directions o$ the cutting and friction forces coincide.

Evolution of Residual Stress During Turning and ...
in cylindrical grinding, normal surface compressive stresses (σ11) have been found perpendicular to the direction of lay and tensile stresses (σ22) in the parallel direction. Only the shear stress σ23 exists in this case. All these stresses also change with depth.

Estimation of residual stresses in gear form grinding ...
2019-6-10 Sallem and Hamdi established an FE model to understand the origin of internal residual stresses during cylindrical grinding of high-speed steel using a resin bond CBN wheel. Salonitis and Kolios [ 13 ] focused on grind-hardening-induced residual stresses and developed an FE model coupled with thermal and elastic–plastic structural analysis.
