Koncept sensitivity - Nástroj pro konstituční modelování materiálu výsypek hnědouhelných dolů
Mašín, David
2004 - Czech
An original approach to constitutive modelling of double-porosity materials is presented in the paper. The approach is based on the parallel in the mechanical behaviour of these materials and sensitive clays. After summary of the framework for the behaviour of natural clays (Cotecchia a Chandler, 2000) a new simple constitutive model based on the Modified Cam-Clay model, which allows for modelling of the degradation of the intergranular porosity, is proposed. Finally, its application to the double-porosity materials is discussed.

2004 - English
Bilaterální symposia mají dlouholetou tradici a jsou organizována na základě dohody mezi DFG a AV ČR každý druhý rok. Umožňují setkání vybraných vědeckých pracovníků, kteří aktivně pracují v experimentální a numerické mechanice pevné fáze, teoreticky i v praxi. Na symposiu dochází k výměně zkušeností, přednáší se zde o právě probíhajícím výzkumu, diskutují se otázky a problémy výzkumných projektů a vzniká se spolupráce jak mezi jednotlivci tak mezi organizacemi The bilateral symposia have a long tradition and are organized on the basis of the agreement between DFG and AS CR every two year. They bring together selected scientists, who are actively involved in experimental and numerical solid mechanics, theoretically and practically, in order to exchange experience,to report on the present state-of-art as well as on runing research projects, to discuss due questions and problems and to promote the co-operation between individuals as well as between institutions

Use of X-ray computed tomography for construction of FE models of bones
Jiroušek, Ondřej; Jírová, Jitka; Máca, J.
2004 - English
The article reports on procedures used for development of FE models of bones on basis of data obtained from series of computed tomography (CT) scans. These models include mechanical properties reflecting the bone inhomogeneity through apparent density which can be easily retrieved from the CT scans. Experimental procedures used for evaluation of mechanical properties of cancellous bone using small samples of cylindrical shape were designed in such a way, which allows for determination of the viscoelastic properties of cancellous bone. Both compressive and tensile specimens are tested while for the strain measurement an optical method utilizing CCD camera of high resolution is used. Relationship between the apparent density and mechanical properties of cancellous bone in a power-law form is proposed.
