Applied hydromechanics, Vol. 10 (82) ¹ 4, (2008) |
The stability of blood vessel is investigated under the pulse wave propagation on the basis of the equations of potential fluid motion and on the Kirchhoff-Love equations of cylindrical shell motion with taking into account the geometrical nonlinearity. The static state due to a transmural pressure and the disturbed motion with respect to this state are considered. It is discovered a region of wave propagation with a negative group velocity and it is shown the possibility of unstable state. |
