Stress-strain analysis of hip spacer
Janáčik, Lukáš ; Valášek, Jiří (oponent) ; Marcián, Petr (vedoucí práce)
This thesis focuses on the stress-strain analysis of the hip joint with a spacer using computational modelling in the form of the finite element method in ANSYS Workbench. The thesis also includes a review of available literature and a brief evaluation of its contributions to the issue. Computational models were created for five variants of geometries of spacers, two different material models of the spacer cores, and two material models (homogeneous and non-homogeneous) of the cancellous bone tissue. The bone cement was evaluated against the limit of brittle strength using the Mohr-Coulomb criterion, which considers different allowable stress values in tension and compression. Core of the spacer was evaluated against yield strength of a material and bone tissue was compared to allowed value of stress intensity before its fracture. The maximum load that the system with a given spacer variant can carry before reaching the first and second limit states was evaluated. Based on the results, it can be determined that the highest load is carried by the intraoperative spacer V2 with either a titanium or steel core, or without a core.
