Effect of shot size in surface improvement via shot peening; analytical, modeling and experimental approaches

This paper discusses about the surface engineering improvement by means of shot peening. Shot peening improves the surface engineering quality by eliminating the tool marks, such as machining, grinding, stamping and other surface defects. Most importantly, the improvements of shot peening are produc...
