MKP analýza únosnosti vícevrstvého železničního podloží
Jiroušek, Ondřej ; Kunecký, Jiří ; Jíra, J. ; Horníček, L.
Numerical investigation of bearing capacity of railway substructure using finite element method and laboratory experiments is presented. A set of parametric FE models is built and unified approach for assessment of bearing capacity of the construction presented. Results are presented in terms of design graphs, where for every type of substructure design resulting bearing capacity is evaluated. Presented methodology is easily extensible for reinforcing effects of layer inclusion, geogrid placement or use of cemented layers.
Numerická analýza zkoušky padostrojem u cyklistické přilby: ručně versus automaticky dělaný model
Kunecký, Jiří ; Micka, Michal
For advanced analysis of performance of bicycle and other sportive helmets, it is advantageous to use FEA. FEA is able to predict the stresses, as well as the acceleration history of the dummy head. The article deals with comparison of two approaches used in the generation of FE model: hand-made model using NURBs modeling software used in design of industrial products and technology based on reconstruction of surface using 3D scanning.
Kontaktní napěťová analýza působení cementované acetabulární komponenty na pánevní kost
Vyčichl, Jan ; Kytýř, Daniel ; Jírová, Jitka
The article deals with problem of interaction between pelvic bone and cemented acetabular component in light of contact stress distribution in subchondral bone. To solving this problem was creating two EF models. First models is inaccurate implanted in pelvic bone and this model is compared with model with ideal position of acetabular component in the pelvic bone.
