Dynamické chování rotorů turbodmychadel

This dissertation thesis is focused on the mathematical modeling and dynamical nalaysis of high-speed rotating machines supported by floating ring bearings. The state of the art is described and the methodology of modelling of rotor-bearing system is described in detail. the gyroscopic...

Mandys, Tomáš
Numerická simulace chování kompozitních konstrukcí při nízkorychlostním rázu

The work is focused on simulation of behavior of composite materials during in case of low-velocity impact loading. The work describes a development of two author's material models of woven composites. The non-linear elastic material model of woven composite with failure reflects th...

Švrček, Miroslav
Spolehlivost reaktoru VVER 1000 s ohledem na poškození vlivem nízkocyklové únavy

The Doctoral thesis deals with problems of fatigue assessment of nuclear reactor components, namely with fatigue assessment of reactor pressure vessel material as well as reactor internals and upper block of WWER 1000. Main goal is the description, interpretation and numerical formulation&#x...

Fišer, Martin
Numerické simulace proudění mělkých vod

This work describes the numerical solution of the mathematical model of the Shallow Water Equations. As the source terms the bed slope source term and the bed friction term are included. At the beginning the mathematical model and the boundary conditions are described. Mathematical...

Bartošek, Jan
Identifikace a lokalizace rázové síly na kompozitové struktuře

This dissertation thesis is aimed at the problem of impact force localization and reconstruction on composite structure reinforced by continuous fibers. Polymer composites are currently applied in important structures like primary structure of airliners. There are many failure mechanisms of compo...

Havelková, Linda
Biomechanický svalově-kosterní model

Presented thesis work is focused on musculoskeletal modeling, especially on muscle forces and moment arms calculation using the new method for muscle path determination. This method is based on obstacle-set method. However, the new torus obstacles are implemented instead of standard obstacle...

Bublík, Ondřej
Aplikace nespojité Galerkinovy metody konečných prvků na řešení úloh mechaniky tekutin

The Ph.D. thesis is aimed at the numerical modelling of compressible inviscid and viscous fluid flows. The spatial discretisation of the governing equations is carried out using the modern discontinuous Galerkin finite element method. The application of this method is performed for the&...
