I am looking for empirical data or equations that predict the increase in local compressive stresses that result from chisel peening.

If a line peen is made using a small rounded slot chisel in a pneumatic peening gun directed at the edge of an aluminum bearing housing, how do you calculate the compressive load on the outer bearing race?

Does the line peen create a compressive load equal to the length x depth of peen x poisson ratio x ultimate stress of aluminum?

Any assistance would be appreciated.
