![]() ELASTIC PROPERTIES EVALUATION OF METALS BY NON-DESTRUCTIVE METHODS. APPLICATION
Ivan Kolarov Analysis of often used non-destructive methods for assessing elastic properties of metals and ments to samples tested to obtain reliable data is done at work. Emphasis is placed on the ments that the tested samples should meet in terms of geometric dimensions, uniformity of the structure and typical reasons for the occurrence of methodological errors. The following methods were considered: vibro-acoustic, ultrasonic and Barhausen noise. Physical foundations of the methods to obtain are described and experimental data are obtained.
The paper is created in the framework of scientific project dedicated to the study of mechanical properties of heat-resistant steels with additional chemical-thermal treatment and will serve as justification for choosing a non-destructive method according to the existing samples for the scientific study. безразрушителна оценка на еластични свойства на метали.Non-destructive evaluation of elastic properties of metalsIvan Kolarov BIBLIOGRAPHY [1] HARRIS’SHOCK ANDVIBRATION HANDBOOK.
