A review study of metamaterial structures for applications in implantology
 Tonhajzer, Michal ; Lošák, Petr (referee) ; Marcián, Petr (advisor)
This bachelor thesis deals with the influence of geometrical parameters variation on the stress-strain states and elastic characteristics of auxetic meta-materials. The research part of the thesis summarizes the basic properties of materials, methods of their determination, specifics in the response of auxetic meta-materials to external loads, occurrence and different types of auxetic structures. The next part of the thesis is devoted to the potential use of auxetic meta-biomaterials in implantology. In the computational part of the thesis, a parametric computational model of a particular auxetic meta-material structure was developed, on which a stress-strain analysis was subsequently performed and the influence of changing geometrical parameters on the material mechanical properties, stress and strain was assessed. Based on the results, two structures were created with parameter combinations chosen to eliminate undesirable effects while maintaining the desired properties. A detailed stress-strain analysis was performed on these two structures and the results were compared with a reference structure. Computational modelling was carried out using the finite element method in ANSYS Workbench 2023 R2.
