Original Abstract
Příspěvek se zabývá chováním BCC ocelí v závislosti na plastické deformaci, rychlosti deformace a na teplotě. Je provedeno srovnání konstitutivních rovnic a pro rovnici Johnson-Cook je provedeno ověření cestou Taylorova testu.
English abstract
The behaviour of BCC steels in dependence on plastic deformation, strain-rate and temperature can be predicted by constitutive equations with material constants. The paper presents comparison different constitutive models suitable for BCC materials. Their parameters are identified with sufficent accuracy by the Taylor Anvil Test.
Key words in English
strain rate sensitivity, strain rate history effect, constitutive equation, BCC steel
