Date of Defense 1997-08-28 Availability unrestricted Abstract An acousto-ultrasonic approach is used to explore the damagedevelopment in tensile shear spot welds during fatigue
loading. There is reasonable data to support the hypothesis
that a decrease in an AU signal is indicative of the presence
of an internal crack and could be used for monitoring and
evaluation purposes.
