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.
Poškození lidské lebky při dopravních nehodách
Jíra, Josef ; Jírová, Jitka ; Kalika, M. ; Klečáková, J.
Problém poranění lidské lebky při dopravních nehodách. Zjednodušený konečněprvkový model sestrojený na základě počítačové tomografie používáme pro analýzu stavu napjatosti lebečních kostí při koncentrovaném napětí a rovnoměrně rozloženém zatížení.
Parametric study of acetabular cup migration
Jírová, Jitka ; Micka, Michal ; Jíra, Josef ; Sosna, A. ; Pokorný, D.
Loosening and migration of acetabular cup into the pelvis belongs to the most serious therapeutical complications. Using computational model we have analyzed stress concentrations at the contact of artificial cup and bone tissue.
Finite element model of human skull for investigation of extreme stress state
Jíra, Josef ; Jiroušek, Ondřej ; Jírová, Jitka
The procedures used in the modelling of the skull from the series of computer tomography.
Analysis of local defects of high-pressure pipelines
Micka, Michal ; Jíra, Josef
In their surroundings the local defects of pipelines influence stress and strain state in the pipe wall. They are significant concentrators of the stress and they have fundamental effect on load-carrying capacity and service life of the pipe. The field of the stress and strain in the surroundings of defects may be detected experimentally or it may be used numerical modelling by FEM. In this paper are presented results of the numerical modelling of the stress state in the pipe wall due to ovality of the pipe also in the surroundings of corrosion pits and further at the place of local inward denting (buckling) of the pipe wall.
Computational model of Swanson's PIP joint implant
Kult, Jaroslav ; Jíra, Josef
The Swanson's proximal interphalangeal joint (PIP) soft skeletal implant was introduced already in the 60's of the 20th century by Dr. Alfred B. Swanson. Its modifications are nowadays produced around the world.
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.
