Description	Problém interakce krve se stěnou aorty je v příspěvku řešen aplikací nesdružené metody. Řešení úlohy interakce se rozpadá na řešení dvou problémů - úloha proudění krve v cévě a úloha elastoplastiky stěny krevní cévy. Úloha je řešena aplikací MKP, krev je modelována jako Newtonova kapalina, její proudění je izotermické a laminární. Stěna cévy je modelována jako kompozitní materiál, který je uvažován ve čtyřech různých vrstvách. Výsledkem řešení je získání indexu poškození pro stěnu cévy na bázi Tsai-Hillova kritéria pro kompozitní materiály. (cs) Blood – aortic wall interaction was investigated in a current work using the uncoupled method. The method is based on alternating, relatively independent solutions of two problems – the problem of hydromechanics for a blood flow in the vessel and the problem of elastostatics for a blood vessel wall, with consideration of appropriate conditions, predescribed on their common bound. In order to solve single problems requested for a complex problem solution the Finite Element Method was used. Blood flow is modeled as isothermal laminar steady flow of incompressible Newtonian fluid. Blood vessel is simplified to a thick-walled linear elastic tube, composed of two fiber-reinforced composite layers. The results of the solution of the interaction problem are used later in order to state the failure index for the blood vessel by means of the Tsai-Hill failure theory obtained for composite structures.
