FIELD: physics.
SUBSTANCE: article is gradually loaded in the region of elastic deformation. The number of acoustic emission pulses and the value of the load are recorded during the loading process. Change in the dimensions of the article is measured. The relationship between stress in the material and time is determined. Distribution parameters of the structural-sensitive parameter in the volume of the material of the article is determined through approximation of the empirical relationship between the number of acoustic emission pulses and the time which is determined using a theoretical curve and the breaking strength of the material of the article is determined using the corresponding equation.
EFFECT: high accuracy of determining the breaking strength of the material of an article.
