Original Abstract

For mathematical description of flow stress dependence on true plastic strain, strain rate and temperature repeatedly verified Johnson-Cook constitutive relations for BCC materials used. these relations are based on real physical charakteristic and they are especially useful for descrption of dynamic pressure tests when inertial forces and mechanical resonance must be taken into account.
