This thesis focuses on stress-strain analysis of the upper central incisor with applied veneer and its variations with proximal fillings and endodontic treatment. The basic materials and veneer types are introduced at the beginning. Next chapter describes the creation of geometric models of a healthy tooth, veneers and fillings. The veneer geometry model has been done in several variants, taking different thickness values, veneer ranges and used materials into account. A finite element mesh was applied to the models. The computation model was solved using the finite element method using the ANSYS 14.0 software in the Workbench graphics environment. The results of the analysis show that the composite material is more suitable for veneers placed partially in the dentin - either with proximal fillings or without them. The ceramic material is a better option for endodontic treatment. Veneers located in the enamel are not significantly affected by the choice of material and the ceramic material is more appropriate only when proximal fillings are applied.

This diploma thesis specialises in stress – strain analysis of the save tooth. Concretely this thesis works with the save tooth with cavity of the I. and II. class. At the beginning of this work you can find description of basic filling materials, different ways of cavity´s preparation and subclassification of cavity. This work describes production of geometric model of health and save tooth with cavity of the I. and II. class. Model geometer of the save tooth was im-plemented in several ways, each one concerning different form of cavity, size of cavity and different filling materials. Final element net was created on the base of these geometric mo-dels. Computational model was created with the help of the programme ANSYS 11.0 in gra-phic environment Workbench and with the help of the final elements method. The results of the analysis are following: Continuity of the save tooth happens to break thereby the whole stiffness decreases in comparison with the save tooth. Two filling materials were used for sanitation of the tooth: amalgam and composite resin. As a result of the analysis I consider amalgam to be more suitable for sanitation of teeth in moral section.

The thesis deals with a comparative analysis of strain of parts using finite element method (FEM) and measurement of the optical system Pontos. Part was used the reflector of Volkswagen Polo. The subject of comparing were the values of deviations optical shield of reflector which excitation random vibration described power spectral density. The thesis presented describes of experimental measurements to obtain the boundary conditions using optical systems. FEM analysis was performed using software ANSYS Workbench 12.

This master’s thesis deals with the computational simulation of low-frequency noise inside the cabin of small commercial airplane VUT 100 Cobra. For this low-frequncy range deterministic methods: Final Element Method (FEM) and Boundary Element Method (BEM) are used for simulation of the dynamic behaviour of the object. FEM has been used to compute eigenmodes and eigenfrequences of the structure of the aeroplane cabin and of the acoustic space inside cabin. Then response to harmonic excitation of engine represented by unit forces in place of contact has been computed. Obtained velocities on the surface of the cabin are then used as the basis for the noise calculation inside the cabin using BEM. After that effect of some construction modifications on sound level inside cabin are evaluated by computational modelling.

The subject of this thesis is to carry out stress-strain analysis of diesel particulate filter support on tractor. So it describes sequence of steps for the analysis model, such as geometry description, mesh generation, applied forces definition and others. Result of the analysis is assessed in terms of strength and improvement was proposed.
