Deformation and stress analysis of the parts of the total replacement of the trapeziometacarpal joint
Svojanovský, Tomáš ; Marcián, Petr (referee) ; Fuis, Vladimír (advisor)
The presented diploma thesis builds on author’s bachelor’s thesis of the similar name which was focused, in particular, on rhizarthrosis. Because of this joint disease, implantations of the total joint replacement are performed. The bachelor’s thesis also served as a familiarization with the finite element method and contact analyses issues, giving a theoretical framework for this diploma thesis. As opposed to that, the diploma thesis aims entirely at deformation and stress analysis of the total replacement. The main objective is to carry out analyses of different variants of geometric models. In addition, there is a tendency to analyze contact pressures of advanced model concerning all the total replacement, bone tissues, ligaments and tendons guaranteeing the static equilibrium of components. The bachelor’s thesis has been developed in ANSYS Workbench, whereas the diploma thesis in ANSYS APDL. Work in APDL allows user to control better over the entire computational process, however, requires more skills and theoretic knowledge. Contact analyses bring a lot of problems associated with convergence of procedures and accuracy of results. Therefore, explanations of important terms and set of recommendations are included for the purpose of easier solving of the contact problems.

Stress and deformation analysis of the stem and cup of the total replacement of the trapeziometacarpal joint
Svojanovský, Tomáš ; Vosynek, Petr (referee) ; Fuis, Vladimír (advisor)
The center of attention of this bachelor’s thesis is stress and deformation analysis of the total replacement of the trapeziometacarpal joint. The first part is formed by medical essence of the matter, namely from the anatomical and pathological point of view. The connecting link between literature research and analysis creates a short introduce to the finite element method. To the stress and deformation analysis itself was used the program ANSYS Workbench 14.5 based just on the finite element method. One of the purposes is to get to know this program and to learn to gain correct results. The main target is to catch and describe stress and deformation of the simplified model of a certain implant. Despite some of the simplifications, resulting values should approach to the real values. Except for the mentioned analysis, there are introduced different approaches, which could be used for the solution. There is also some comparison of advantages and disadvantages of particular approaches.
