Shell component like specimens were designed and then produced. One side of surface was shot peening processed by wet blast processed and the back surface was not. Experimental date and analytical results indicated that compressive residual stress exists on the back surface
the amount of residual stress is higher on pure shell specimen than shell structure reinforced by ribs on back surface
tensile stress could be produce by increasing transverse stiffness
residual stress is controlled by parameters of wall thickness and shot peening intensity and it can be decreased by the lower shot peening intensity or increasing the wall thickness. The founding of this research can be helpful in improving shot peening parameter and modifying the topology of components.
