Research abstract

CURRENT SHOT PEENING TECHNOLOGY DOES NOT OFFER THE CAPABILITY TO ACCURATELY PREDICT FATIGUE LIFE BENIFITS. RECENT TEST RESULTS IDENTIFY A HERETOFORE UNDOCUMENTED SURFACE INTEGRITY PHENOMENOM ASSOCIATED WITH PEENING AT RELATIVELY HIGH INTENSITIES WHICH HAS BEEN LINKED TO PREMATURE SPECIMEN FAILURE AT SPECIMEN FAILURE AT FATIGUE LIFE LOWER THAN THAT OF UNPEENED SPECIMEN. DATA PRESENTED BY SEVERAL AUTHORS AT THE FIRST INTERNATIONAL SHOT PEENING SYMPOSIUM INDICATES THAT CURRENT MILITARY AND INDUSTRY SPECIFICATIONS CONCERNING SUGGESTED SHOT PEENING LEVELS ARE LARGELY INADEQUATE AND MAY IN SOME CASES BE DAMAGING TO FATIGUE LIFE AND STRESS CORROSION RESISTANCE. A METHOD IS PROPOSED FOR DEVELOPING A MATHEMATICAL MODEL WHICH WOULD BE CAPABLE OF PREDICTING THE PERCENTAGE OF FATIGUE LIFE INCREASE THAT COULD BE OBTAINED FROM PEENING, AND WHAT PEENING PERAMETERS AND PEENING INTENSITY CORRELATED WITH OPTIMUM FATIGUE LIFE.
