| Description
| - A model of elastic artery is presented that describes the vessel as a two-layer thick-wall cylindrical tube where each layer is treated as a composite of two constituents: the passive fibres (representing the collagen or elastin fibres) embedded in the isotropic matrix (representing other constituents including the extracellular substance). This mathematical model involves many constitutive parameters which must be identified using experimental results of a macroscopic specimen of the healthy artery. The proportional representation of the basic components in terms of volume fractions (also the elastin length density, the diameter of the aorta and the thickness of the wall) were determined using both microscopic and macroscopic morphometry of the tissue samples. In order to find the constitutive parameters, quasi-static uniaxial traction tests of samples from porcine aorta were performed. Methods based on optimization are adopted to the material identification.

- V tomto příspěvku představujeme model elastické artérie, která je modelována jako dvouvrstvá silnostěnná trubice, kde je každá z vrstev popsána jako kompozit dvou prvků: pasivních vláken představujících kolagenní či elastinová vlákna, a isotropní matrice, jež zahrnuje ostatní složky včetně mezibuněčné substance. Tento matematický model obsahuje řadu konstitutivních parametrů, které musí být identifikovány na základě experimetu na vzorku zdravé aorty. Proporcionální zastoupení základních komponent vyjádřených objemovými poměry, rovněž tak i průměr aorty a tloušťka stěny byly určeny použitím mikroskopické a makroskopické morfometrie tkáňových vzorků.
