description: The subject of the graduate qualification work is "Evaluation of thepossibility of determining the strain dependence during high-speed uniaxial tension by magnetic-pulse method".The given work is devoted to determining the acting factors that influence the measurement of the strain relation during high-speed uniaxial tension by magnetic-pulse method using the Hopkinson-Kolsky measuring bar. The research set the following goals:1. Study of mechanical properties of materials and the process of their deformation.2. Study of models of high-speed deformation and methods of testing the dynamic properties of materials.3. Calculation of magnetic pressure in a system of flat conductors.4. Modeling of deformations of working part of specimen as well as steel measuring rod connected to it.5. Analysis of the obtained results.Â As a result of the work, it was determined that the use of the Hopkinson-Kolsky measuring bar during high-speed uniaxial tension of the material by magnetic-pulse method makes it possible to obtain the stress-strain curve with 10% accuracy and to estimate the deformation rate.
