Abstract:  
A method and system for nondestructively measuring surface compression layer depth including obtaining profile data of a peened workpiece surface and determining a total plastic upset depth for a selected dent, the plastic upset depth being approximately equal to the dent diameter. The peening operations may then be adjusted, if needed, so that subsequent peening more closely conforms to predetermined, desired peening results.
