    Abstract

    A new method has been developed for in situ compliance measurements on fatigue crack growth specimens. Crack lengths may then be inferred from the compliance measurements. The method is particularly well suited for autoclave testing where direct observation of the specimens is impossible. The new method uses the change in induced eddy current fields with specimen loading as a measure of specimen compliance. Calibration of the device in various environments and temperatures is discussed.
