Original abstract
Proposed paper deals with the application of plastic response with directional distortional hardening (DDH) in uncoupled ductile fracture model and comparison of the results with the same ductile fracture model based on isotropic J2 plasticity. The results of simulations have proven not negligible role of model of plasticity and the response of the model with DDH plasticity is closer to reality then the one of the model with isotropic plasticity.

Předložený článek se zabývá aplikací plastické odezvy se směrovým distorzním zpevněním (SDZ) v modelu nesvázaného tvárného porušování a srovnáním výsledků s tím samých modelem tvárného porušování založeným na izotropní J2 plasticitě. Výsledky simulací prokázali nezanedbatelnou roli modelu plasticity a odezva modelu s SDZ plasticitou je blíže realitě než ta modelu s izotropním zpevněním.
