Paper Abstract

Light-weight and multiplexable, Fiber Bragg Grating (FBG) optical sensors allow the integration of many sensors along a single electrically passive and electromagnetic interference immune optical fiber. In this paper, we describe the use of multiple FBGs for monitoring and early stage detection of fatigue crack growth. We provide experimental results over a range of temperatures for fatigue crack monitoring in titanium alloy specimens subjected to periodic loading for tens of thousands of cycles and demonstrate detection of early-stage fatigue crack extension.
