Plastic deformation of metallic materials and alloys is a complex process that depends on a number of factors with the effect of strain rate being of particular importance. Dynamical tests are used for determination of mechanical properties. Split Hopkinson Pressure Bar Test is often used for these experiments. The paper deals with possibilities of testing device for flat bars adapted at Hopkinson test. The aim of this work is concentrated on strain rate influence on DC 01 steel too.

Keywords: Flat bars, Stress-strain, Strain Rate, Carbon Steel, Split Hopkinson Tensile Bar test-SHTBT
