Original abstract

The paper deals with mathematical models of BCC material flow stress, reflectin the influence of high strain rates and temperature. The Johnson Cook constitutive equation was proved to be very suitable for strain rate range 1 to 1000 s1. The definition of equation parameters was based on the impact Taylor test.

Czech abstract

Příspěvek se zabývá matematickým modely BCC materiálů (křivkami napětí deformace) s vlivem rychlosti deformace a teplot. Konstitutivni rovnice Johnson Cooka se jeví jako vhodnou pro rozsah rychlostí deformace 0,1 až 1000 s1. Definice parametrů konstitutivní rovnice byly získány cestou Taylorova testu a jeho shody s výsledky simulace kompresního testu.
