I am reviewing the value of retaining a shot peen process on a carburized, low alloy pinion. The pinion is subjected to an initial shock load at start-up followed by a 1-3 sec duration steady load. Operating speed of 3-5k rpm and it must last in the neighborhood of 10k start cycles. The application is successful with the peening opertion and has never been tested without it.
My experience with the use of shot peen has been primarily qualitative as a measure to boost fatigue resistance and have never been tasked with quantifying its importance. Is there any means by which to quantitatively review the effectiveness of shot peen? Do I isolate the component and look only a repetitive loading via testing or are there new analytic measures?
