Measurement of Residual Stresses in Difficult Locations

Abstract

The Air Force identified measuring stresses in hard-to-access locations as a major concern. Detrimental stresses in these locations lead to expensive loss of use, inspection & repair costs, and potential loss of aircraft and personnel. Aluminum alloys were the structural materials identified as the highest interest of the Air Force. A small XRD system named MAX (Miniature Advanced X-Ray) was developed to fit inside a 6" orifice. MAX is a very portable XRD system that can make quality residual stress measurements quickly in hard-to-access locations on aircraft. The system can be carried by one person and configured for measurements in less than 5 minutes. The user-friendly software controls the system and has a powerful peak analysis routine. Comparison of MAX's data to other XRD systems show that residual stress measurements are reliable.
