The Conditions of Vibrations and Collapse of Human Blood Vessels
Original language description
Biomechanical material properties of arteries and veins are investigated experimentally and theoretically. The main goal of the histological research and the developed theory is to formulate the biomechanical conditions (geometrical dimensions, viskoelastic properties of veins and blood fluid flow conditions) at which an unstable behavior or even the vein collapse can occur. One dimensional fluid structure approximation was starting point for the theoretical analysis of fluid flow through highly elasticcollapsible tube. Provided that the neo-Hook's material model was applied the analytical formula for the collapse conditions was found. It was proved that for the brain vein contraction about 5%, the vein collapse can occurs even under normal physiological condition into vessels - the angiosynizesis. The fluid structure interaction is studied experimentally on the special experimental line. Latex tubes with variable inner diameter and wall thickness are used as specimens.
