dc.description.abstract Hlavním cílem této práce bylo vyvinout novou cell-centered numerickou metodu pro hydrodynamiku v 1D, 2D kartézské a 2D rz cylindrické geometrii a pro problémy elastoplas- ticity v 1D a 2D kartézské geometrii. cs
dc.description.abstract This thesis deals with a novel cell-centered numerical scheme for calculating hydrodynamics and elastic-plastic flows in Lagrangian coordinates. The physical fluxes are discretized using the Richtmyer two-step predictor-corrector finite volume formulation of the Lax-Wendroff scheme. To mitigate non-physical oscillations due to LW dispersivity, HLL based artificial dissipation is added to momentum and energy equations. The numerical performance of the method is illustrated on several convergence rate analyses and typical benchmark tests. en
