Shot peening
Shot peening
(OP)
It is known that shot-peening increases the fatigue strength of a material as it leads to residual compressive stresses in the surface and subsequently increases the resistance to crack initiation and growth. My question is, does shot-peening affect the resistance to static stresses too? or not since it affects only the surface of the specimen?

RE: Shot peening
It is customary to use shot-peening and or shot-blasting as secondary or finishing operation in manufacting parts such as Leaf Springs for suspension system of heavy trucks or trailers. .This finishing operation comes after heat treatments( Right after Oil quenching)in which it improve and relaeses the residual stress.Thin in turn extends the perfomance of stack of leaf springs under operation.See some immages:{ https://www.google.com/search?q=leaf+springs+for+t... }
