Abstract:

The purpose of the program was to determine the applicability of a noncontracting infrared detection system for use with fatigue specimens in the sonic test facility. The breadboard model of a detection system was constructed. The system used a radiative heat source and an infrared radiometer to detect changes in the heat transfer characteristics due to fatigue flaws in structural metals. Tests of the system were performed on artificial and actual flaws. The system proved able to detect the larger fatigue failures. These results demonstrate the feasibility of the system and further investigation with the construction of a prototype system is recommended. Author
