Abstrakt: The mixed formulation of the finite element method with the separately interpolated pressure is used for the numerical simulation of the fluid structure interaction. To describe a wider class of problems we consider in the simulation the three material models: the Neo-Hookean, the isotropic Gent model and the anisotropic Gent material model to include the influence of collagen structure of blood vessels. The fluid is modelled as Newtonian liquid. The strong coupling of both structure and fluid solvers allow us to simulate large deflection oscillations of the structure. The special experimental mock up line was designed for the investigation of unsteady fluid structure phenomena. Latex tubes with variable inner diameter and wall thickness are used as specimens. The qualitative and quantitative fluid structure phenomenon investigation are performed for both the continuous and pulsatile flow.
