A stress analysis of notched specimens under multiaxial loading
Václavík, Martin
Linear stress analysis of notched specimens under proportional multiaxial loading is described in the paper. For stress-state analysis in specimen critical place FEM is used. Stress concentration factors are compared to theoretical values according to Tresca and von Mises yield criteria.
Fundamental aspects of acetabular cups of THR
Jírová, Jitka ; Micka, Michal ; Jíra, Josef ; Sosna, A. ; Pokorný, D.
Conical acetabular cups, which migrated across lamina in the course of years, were retreived and evaluated. Just at the contact between bone and artificial material of the implant overloading or on the contrary insufficient loading of the trabecular bone tissue and undesirable micromotion of the acetabular implant were observed.
Modelling of Strain State of Cementless Spherical Acetabular Cup
Jírová, Jitka ; Jíra, Josef ; Micka, Michal
The paper deals with cementless acetabular cup - Beznoska type.This cup is made of 1 mm thick titanium covering and polyethylene inner layer. The subject of the research was to gain basic kmowledge of the behaviour of the composed structure using strain gauge measuring and 3-D FEM by applying ANSYS programme.
Modeling of specific cathegory of bi-material bodies with respect to fracture mechanics\' problems solution
Bareš, Pavel
Paper deal with numerical calculation problems of crack terminating throught an interface between two elastic identical materials with different yield stresses. Calculations are based on finite element method. Crack behaviour is described here by means of crack tip opening displacement CTOD assessed as a translation vector component on the 4. node from the crack tip lies on the crack face when the eight-node elements are used.
Comments on the application of analytical transformation models and FEM models in the framework of the SBRA Method
Marek, Pavel ; Guštar, M.
The paper turns attention to the main differences between the individual models and between the approaches to the reliability assessment as well between the results.
