FIELD: nondestructive testing.
SUBSTANCE: method comprises exciting natural elastic acoustical vibration inside the part by means of short-term striking on the part and recording and analyzing the parameters of the acoustical vibration. The rate of decaying of the logarithmic envelop of the main mode of vibration is used as an informative parameter.
EFFECT: enhanced precision.
