Description

This work combines fracture mechanics and ultrasonics inspection techniques in the non-destructive evaluation of cracks that commonly occur in fretting fatigue. The first part of the study was a fracture mechanics analysis [1,2]. This was necessary to estimate the depth of penetration of the normal stress field under typical 2-D fretting fatigue conditions, which control crack shape and hence served as a guide in the choice of a suitable inspection technique (wave type) and frequency.

Characterization of “Kinked” Surface Cracks Using Rayleigh Waves
