FIELD: the invention is designed for non-destructive control of durability of products. ^ SUBSTANCE: the essence is in that in the process of non-destructive control of durability of products the product is evenly or in discrete steps evenly loaded and the number of impulses of acoustic emission and their amplitudes are registered in the processes of loading. At that the summary amplitude zeta of impulses of acoustic emission is additionally determined, the relation of logarithms of the summary amplitudes are determined in specified moments of time ti, tj, the law of distribution of the number of impulses of acoustical emission along the amplitudes is determined with simultaneous determination of nominal voltages sigmai, sigmaj in the controlled zone of the product in the moments of time ti, tj correspondingly. According to the results of the tests the parameters of condition of the material of the controlled product YAE according to the mathematical formula. ^ EFFECT: increases accuracy of results of acoustic-emissive control of the product, determination of distinct classification of the degree of the danger of sources of impulses of acoustical emission. |
