Original abstract

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.

Článek předkládá výsledky v podobě konstitutivní rovnice pro BCC ocel 12 050 dle modelu Johnsona-Cooka. Ověření bylo provedeno cestou TAT a numerickou simulací programem LS DYNA 3D. Pro lineární citlivost na rychlost deformace konstitutivní rovnice dle Johnsona Cooka dobře vystihují fyzikální parametry chování BCC ocelí v procesu plastické deformace za studena.
