Stress analysis of the total hip joint endoprosthesis head under oblique loading
Janovský, Martin ; Janíček, Přemysl (referee) ; Fuis, Vladimír (advisor)
This diploma thesis is concerned with the stress analysis of the total hip joint endoprosthesis ceramic head under oblique loading. Load was obtain from experimental in vivo measurement on three patients, whereas two of them was the same weight. As input variables were use contact forces, especially knee bend and standing on one leg. Furthermore they will be considered shape deflections from ideal cone, especially circle deviation, cone deviation and cone plus circle deviation together.

Stress analysis in ceramic head of the hip joint endoprosthesis under oblique load
Fuis, Vladimír
Problem of the stress in the ceramic head of hip joint endoprosthesis pressed on the stem under oblique loading is solved in this paper. Oblique loading simulated the physiologi-cal conditions in vivo. The axis-symmetric production inaccuracies (deflection of nominal degree of taper) of the head - stem conical joint are considered. Computational modelling is realized by FEM - system ANSYS.
