Abstract

A global non-destructive testing technique for detecting cracks in metal parts has been developed and the factors affecting its sensitivity investigated. A sample is excited at very-high-order modes of vibration at two frequencies and the frequency mixing measured. Experiments with fatigue-cracked steel beams demonstrate that these defects produce a strong mixing effect and that the signal relating to the frequency mixing is sensitive to the length of the crack. The sensitivity is also shown to be reliant on the modes of vibration used.
