Abstract:

The program is concerned with the advancement and development of the inductive sensing system. The system significantly enhanced in its ability to detect early fatigue damage in 6061 T-6 aluminum. Samples were fatigue cycled up to 2,000,000 cyles, and crack signals have been observed as early as 9.7 of life. The system greatly enhanced in its sensitivity to cracks and its insensitivity to extraneous factors such as probe proximity and generalized surface damage. This increased sensitivity to flaws, coupled with the ability to selectively disregard extraneous surface conditions or probe proximity, significantly advanced the state of the art in nondestructive testing.
