چکیده انگلیسی
Modernization and application of flying wheel machine for dynamic testing of sheet metal samples were researched. The machine gives constant velocity of displacement of grips with easy velocity control. The sample shape and dimensions, holders, the measurement system based on single Hopkinson bar were prepared. High kinetic energy of the forcing disk assures almost constant velocity of the test independently of dimensions and properties of samples as well as the stiffness of the measurement bar. The tests show that Young's modulus lower holder should be equal to modulus of sample material, the significant decrease in disturbance of tensile force course was obtained.
