Originální abstrakt

The paper presents the results in the form of constitutive equations for grade 12 050 carbon steel according to the Johnson-Cook model. In the verification the TAT method and numeric simulations with the help of the LS DYNA 3D program were used. For the linear sensitivity to strain rates ranging from 10 to 103 s-1 the Johnson-Cook constitutive equations express well the physical parameters of the behaviour of BCC steel during plastic deformation.
