Ultrasound control and study of physical model conduct of 20 gl steel tensile

Abstract

One of the most important problems in solid state physics is searching new patterns in the performance of the physical characteristics of metals in the external radiation on them. This research deals characteristics of ultrasonic testing on plastic molded metal, based on the connection speed of ultrasound with elasticity module and the analysis of the stress-strain on the example of steel 20GL brand. According to the results of the experiment there is a new theoretical basis of a physical model of metal pattern in tension. It was found that the previously proposed a parabolic response function is not applicable when there is maximum deformation. It was given an analytical expression for the response function. It is shown that as the response function fits the function displayed in the form of an ellipse. It was found that exactly that function describes the experimental data satisfactorily.
