Description

Resonant Inspection (RI)* is an important new technique for non-destructive evaluation of manufactured parts. RI mechanically vibrates a part and detects defects based on changes in the pattern of vibrational resonances. RI measures the “whole body” structural response of the part rather than scanning for defects, as do most other NDE techniques. As a result it is accurate, fast, inexpensive and requires no human judgment, so it can be used for 100% inspection. However, since RI infers the presence of a defect from the resonant pattern of the whole part, up - front engineering is required to develop a detection algorithm that correlates the changes in resonance pattern to the presence of defects of interest.
