Relaxace v mechanice kontinua tuhé fáze

2010
This work deals with the modelling of shape-memory alloys, in particular with the steady-state model of martensitic thin films. After the introductory motivation the crystallographic structure of the materials is described followed by the introduction of the link between the lattice and continuum model.

Hamiltonova funkce v mechanice klasické a kvantové

2016
In this work we will examine an on-shell action, its basic properties and its relation to transition amplitude. Derivatives of on-shell action with respect to position and time are equal to momentum and energy. On-shell action of a system is sufficient for determining the trajectory describing time evo- lution of the system.

Využití zobecněných funkcí v mechanice kontinua

Tato práce se zabývá využitím distribucí neboli zobecněných funkcí k řešení nestacionárních okrajových problémů v mechanice kontinua. Nejprve je zavedena teorie distribucí a jejich definice jako spojitých lineárních funkcionálů na prostoru testovacích funkcí. Druhá část teoretické kapitoly představuje Laplaceovu integrální transformaci.

Tensory a jejich aplikace v mechanice

The tensor theory is a branch of Multilinear Algebra that describes the relationship between sets of algebraic objects related to a vector space. Tensor theory together with tensor analysis is usually known to be tensor calculus. This thesis presents a formal category treatment on tensor notation, tensor calculus, and differential manifold.

Implicitní konstitutivní vztahy v nízkodimenzionálních modelech v mechanice kontinua

2020
We study implicit constitutive equations and their possible applications in the description of the elastic and plastic response of isotropic solids. We develop a thermodynamic framework for the elastic and plastic response of isotropic solids and we perform simple numerical simulations of the elastic as well as plastic response of solids (beams) using ...

Použití metody spektrálních elementů v mechanice tekutin

2007
This work presents application of spectral element method (SEM) for solving partial differential equations. This method can be seen as combination of spectral method (SM) and finite element method (FEM). Computational domain is decomposed to smaller elements, what enable description of more general geometries.
