Annotation: Dizertačná práca sa zameriava na vypracovanie a numerické overenie materiálového modelu na modelovanie správania sa a poškodenia kovových materiálov v ktorých konečné deformácie sa prebiehajú pri extrémnych rýchlostiach pretvorenia s možným prechodom húževnatého charakteru porušenia materiálu na krehký. V Lagrangeovom opise konštitutívnej rovnice materiálu sa využíva nelineárna mechanika kontinua konečných deformácii termoelastoplastického materiálu zdokonalená na Ústave aplikovanej mechaniky a mechatroniky, ktorá je schopná objektívne a termodynamicky konzistentne formulovať konštitutívnu rovnicu materiálu v rýchlostnom tvare.
Annotation in English: The aim of the PhD thesis is to develop and verify a material model for numerical simulation of behaviour and material degradation of metallic materials in which finite deformations take place at high strain-rates including ductile-to-brittle failure mode transition. In the Lagrangian formulation of the constitutive equation of the material there is used the nonlinear continuum theory of finite deformations of thermoelastoplastic material developed at the institute of applied mechanics and mechatronics, which can describe the rate form of the constitutive equation of the material in an objective and a thermodynamically consistent manner.
