EFFECTS OF SHOT PEENING ON HARDNESS OF 18CRNIMO7-6 STEEL BASED ON FINITE ELEMENT ANALYSIS

Jixie qiangdu, 2022
So far, most of the numerical studies on shot peening are limited in the effects of shot peening parameters on the residual stress and surface morphology. There is still lack of numerical research on shot peening parameters on the hardness.
