Stress - strain analysis of jaw with tooth implant type MTI
Petrlíková, Helena ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma work is oriented on the deformation and load stress analysis of the jawbone with the razor-blade dental implant of the company MTI. There is a literature search on this theme in the beginning of this work. Deformation and tenseness of the system is done by computerized method FEM. There is detailed description of creating the computational model in this work. The geometry model of the system was created in the 3D CAD design software SolidWorks. Discretization, model of constrains and load sets including own solution was created in the ANSYS Workbench. On the basis of solutions with different load sets, which are presented in this work, is created a deformation and load stress analysis for two razorblade implant of copany MTI.

Stress - strain analysis of inferios limb with fixator type Poldi 7
Pásek, Jiří ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma thesis deals with stress-strain analysis of inferious limb fixator type Poldi VII and tibia, whereupon is applied. In work is discribed creation of a geometry model of fixator and tibia, her discretization, loading and solving. Tibia was load by torsional moment and his magnitude was 10Nm. Then was perform a numerical solution in FEM system ANSYS Workbench 11.0. Further was effect biomechanical study about osification of broken part. Tibia was load by force, which evokes upright standing on both limbs.

Biomechanical research study of skull plates and implants
Vystrk, Tomáš ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
Cranial implants along with fixators are used to restore the function of the damaged area of the human skull, where due to disease or injury the defect was created. When assessing the suitability of the implant and fixators the mechanical properties are significant. With this the material and shape of implant and fixators are related. The implant must be suitable with human bone tissue and also be able to withstand long-term loading. This paper summarizes the present knowledge regarding the design, manufacture and application of cranial implants. Next the stress-strain analysis of the loaded scull with irregular shaped defect, placed implant and fixation system is provided.

Strength analysis of cutting tools
Petrlíková, Helena ; Madaj, Martin (referee) ; Zouhar, Jan (advisor)
This work is focused on the stress-strain analysis of a cutting tool. At the beginning, the study of available literature and scientific articles relating the topic is carried out. The solution of stresses and strains in whole real system has been carried out based on the computational simulation using the finite element method (FEM). The work contains a detailed description of the creation of the computational model. Model of geometry of the system has been created in the SolidWorks program. Computational simulation including the solution was implemented in the ANSYS Workbench program as well as in the classical environment of ANSYS 12.0. This work includes the presentation of results and subsequent stress-strain analysis of the cutting tool. Last part of this work deals with the modal analysis and harmonic analysis of cutting tools made in classical environment of ANSYS program.

Stress analysis of rotor packet of synchronic generator
Bureš, Jiří ; Houfek, Lubomír (referee) ; Petruška, Jindřich (advisor)
This diploma thesis deals with distribution stress and strain of sheets metal of rotor packet and in critical locations of supporting bars of synchronous generator. These variants are calculated and one another comparison of analytic calculation results, numeric calculation of 2D model and numeric calculation of 3D model in three vriants ( with bars of rectangle section, circular section, with upper radius). The calculation include influence of thermal expansion, centrifugal force, interference of the packet on the shaft and prestress in the axial direction of bolt. To creation of geometric model and numerical calculation is used program ANSYS 11.

Stress-strain analysis of skull implant
Hřičiště, Michal ; Borák, Libor (referee) ; Marcián, Petr (advisor)
Lebeční implantáty se používají jako náhrady částí lebečních kosti, které v důsledku zranění nebo nemoci ztratili svou funkci. Důležitým faktorem, který ovlivňuje funkci celé soustavy implantátu, jsou jeho mechanické projevy. Tato práce stručně shrnuje současné znalosti v oblasti rekonstrukce lebečních defektů a popisuje srovnání různých tvarů stěn implantátu vytvořených z různých materiálů, na základě deformační napěťové analýzy modelu neurocrania s umístěným implantátem, zatíženým nitrolebečním tlakem a vnějším zatížením.
