Abstract

In this paper viscous properties of both the vessel and blood are taken into account. The motion of viscoelastic vessel is described by the Kirchhoff-Love shell theory, the blood motion by the equations averaged over the cross-section. Earlier in the similar statement the problems have been considered for a semi-infinite uniform vessel and for jointed vessels. This model demonstrates the attenuation and delay of pulse with increasing distance from the input and the concentration of shear effort at running the pulse to the insertion. The existence of the transition junction zone yields a concentration of biomechanical stresses and a transport of substance. The latter in this turn, can lead to pathological changes and thrombus formation.
