Hemodynamics and Mechanical Behavior of Pathologically Tortuous Carotid Arteries

The numerical analysis of blood flow through anatomically real healthy and pathologically tortuous bifurcation of human carotid was carried out. Experimental velocity field data in carotid bifurcation were obtained using noninvasive technology. 3D computer models based on computer tomogram were built. The material of the wall is assumed to be linear isotropic.

Analysis of Healthy and Pathological Human Willis Circle Arteries

The aim of this research is to explain initiation, growth and rupture processes of intracranial aneurysms from the mechanical point of view. Results of mechanical testing experiments of intracranial arteries segments are presented, method of obtaining hyperelastic material constants is described. Several boundary problems which simulate blood flow through the arteries were solved with the help of finite element method.
