Application of 'FRACTOMAT/KRAK GAGES' to Crack Growth Measurements in Structural Components.

Abstract

Accurate crack size measurements are required for fracture mechanics' solution to component life predictions. Usual methods have limitations and the developement of a real-time crack measurement technique would be of great value. The operation and accuracy of the 'Fractomat' device for crack growth measurement is assessed during its normal application to standard fracture mechanics specimens. The technique is found to be at least as accurate as surface microscopic examination. The further application of this technique to crack measurement of in-service flaw location and orientation are known. The potential application is then demonstrated by examination of crack growth during the laboratory fatigue fracture of a typical aircraft structural component, the forward wing trunnion of the CF-100 aircraft.
