FIELD: nondestructive testing. SUBSTANCE: method consists in measurement of parameters of signal of electromagnetic emission produced by dynamically loaded article with the aid of electromagnetic field transducer. Parameters are used to determine development and state of defects in article. Transducers of electromagnetic fields embrace cross-section of article of electrically conductive materials. Used as parameters of signal of electromagnetic emission are continuously measured amplitude and frequency of induction emf at transducer output and shape of induction emf signal and compared with those obtained on detectless article. EFFECT: higher confidence and reliability of prognosis. 3 dwg
