N2 - Results of dynamic tests of pipe steel of strength category of 650 MPa on dynamic strength, fluidity and fracture toughness are presented. The stress-strain curves for shock tension and the dependence of the ultimate destruction characteristics of materials on the strain rate and temperature are constructed. To obtain the parameters of dynamic fracture toughness, modifications of the Kolsky method were used on tension a solid cylindrical specimen weakened by an annular V-notch. The work and fracture toughness are determined. To describe the velocity dependences of the utmost characteristics of the fracture toughness, a well-known Morozov-Petrov incubation time criterion was used.
