FIELD: fault detection.
SUBSTANCE: can be used: for non-destructive testing of metal damage. Essence of invention is determine the time delay of propagation of the elastic wave, while the determination of the time delays is performed for one type of volumetric elastic wave at different temperatures and determines the damage of the material using the given mathematical formula.
EFFECT: reducing faults and reducing the complexity of determining the damage to the metal.
