Abstract
To find effective parameter for quantifying fatigue crack defects, second harmonic motivating efficiency was used in this paper as the feature parameter of quantitatively identifying fatigue micro-crack defect of metal component, and the deduction of theory formula was obtained. Moreover, its correction was proved.
