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.

Stress - strain analysis of jaw with tooth implant type VNI
Školník, Roman ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
This diploma thesis is dealt with stress-strain analysis of jowl with teeth implants. Teeth implants when locked in place (jowl) have the ability to replace and be used in the same way as the missing teeth. The implant creates a pillar column in the buccal cavity and then the tooth cap or bridge is secured on the pillar column. In this diploma thesis it is described as a solution of stress and strain of two types of cylindrical teeth implants VNI. Thesis specializes on the influence of deviation implant from the vertical axis. The solution is accomplished in program ANSYS Workbench by Finite Element Method (FEM). The geometric models are made in program SolidWorks 2005.

Stress - strain analysis of jaw with tooth implant type BOI
Marcián, Petr ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
Submitted master thesis deals with stress - strain analysis of jaw, with dental implant. The implant serve as a suitable pillar for crown or dental bridge, when one or more teeth are lost. The project is oriented on BOI (basale - oseo - integrable) dental implant type, which is produced by DENTALIHDE company. Stress – strain condition of the mandible system with implant have been established by computational simulation, with use of the final elements method. Important part of down jowl is simulated on with EDS and EDDS applied types of implants. After implementation the implant begins to heal. Therefore the special attention is paid to stress - strain states on various level of osteointegration. There is a detail description of production of single part computational model and his solving in the master thesis. Presentation of large chapter with results and subsequent alteration stress - strain analysis is part of the master thesis. Program SolidWorks 2005 was used to create the geometric model. Computational model and the actual solving was accomplished with use of ANSYS 11.0 and ANSYS Wor-kbench systems.

Stress - strain analysis of total hip replacement - type Santori
Huťka, Pavel ; Fuis, Vladimír (referee) ; Florian, Zdeněk (advisor)
Submitted Diploma thesis deals with stress-strain analysis of deformation proximal end of femur with applied total hip joint endoprosthesis (replacement) – shortcut type. To identify deformation and tensity (stress) was used computational simulation by method of final elements. Have been created two computational models TEP- type Santori and type DePuy Proxima. Geometry model Santori was created on low level model geometry through the use of X-ray photograph. Principle of geometry model type DePuy Proxima was real Femoral stem endoprosthesis which was scanned on scanner ATOS. Geometry of both these replacements were set up in program Rhinoceros 4.0 and then execute in program CatiaV5R17. Data for geometry model of femur were gained from CT chains. Material model of femur have been crated in two variants. The first one looks at structure bone tissues and the second one were created by Gruen´s zones. Femoral Stem was weighted by static equivalent resultant force acting in hip joint. Computational model of system and self solution, including depiction results, was done by ANSYS Workbench 11.0 for four model variants.

Stress-strain Analysis of Tractor Exhaust Tail-pipe
Lébl, Jan ; Píštěk, Václav (referee) ; Dundálek, Radim (advisor)
This diploma thesis deals with the strength and frequency analysis of tractor exhaust pipe, which is being developed as an economic alternative in the preparation of construction for use in convertible tractor’s in the Zetor Tractors company. First, modal analysis is performed to determine the natural frequency of the exhaust pipe. In the next section it deals with stress-strain analysis to assess the overall structural strength of the exhaust pipe. At the end is performed thermodynamic analysis to assess the thermal resistance. For these calculations was used the finite element method (FEM) using computing software ANSYS 13.

Stress-strain analysis of skull implant using analytical and numerical solution methods
Sehnal, Dominik ; Borák, Libor (referee) ; Marcián, Petr (advisor)
This thesis focuses on stress-strain analysis of cranial implant. The research of literature available dealing with the problems of cranium implants and the solution of the stress analysis is incorporated. Furthermore, the basic information about an approach to the design and fabrication of medical implants is included. Subsequently, two ways of possible solution to the method of stress-strain analysis on an computational model of cranium (partially spherical shell) are introduced. These are analytical and numerical solution by using the finite element method in the Ansys programme. The calculated solutions of a particular type of task about deformation and stress are compared and evaluated with the solution acquired from the high level computational model of cranium with shaped irregular implant applied.

Biomechanical analysis of bone implant contact for different type of implant profiles
Svobodová, Miriam ; Chamrad, Jakub (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with the assessment of the influence of the dental implant diameter placed in the bone with a fixed connection between the bone and the given implant on the strain into the bones around the implant,the deformation throughout the system and the stress in the implant. Computational modeling with finite element analysis was used to solve a given task. Two types of the implants with different diameters and bone model with a beam structure and different layer thickness around the implant were modeled. Used material was homogeneous, isotropic and linearly flexible. The overall analysis was carried out at the 2D level. The results show different values for different diameters and thickness of the layers.

Stress-strain analysis of dental implant inserted in maxilla
Dušková, Tereza ; Hájek, Petr (referee) ; Marcián, Petr (advisor)
Variety of problems can appear when introducing dental implants, especially to in the maxilla. Biggest problems are caused by insufficient quality and volume of the bone tissue of the alveolar process. This thesis focuses on stress-strain analysis of an implant introduced in the maxilla. Mechanical interaction between the implant and bone tissue is solved using computational modelling with the finite element method. From analysis of results, it was discovered that deformation and tension of the implant are influenced by the direction of the load, osseointegration and thickness of the cortical bone tissue. In the anterior region, it is necessary to work with other types of load than axial.
