FIELD: mechanical engineering.
SUBSTANCE: method comprises measuring initial value of a characteristic of damage ability of material before the beginning of its use and rate of variation of the characteristic within a chosen time interval, extrapolating the dependence to the limit value, and determining the expected time before damaging and residual service life of the material on the basis of an analysis of the results of the measurements.
EFFECT: enhanced reliability.
