Effect of Visco-Elasticity of an Orthotropic Arterial Wall on Pulse-Wave Propagation

Abstract

The problem of harmonic pressure wave propagation through a viscous fluid contained in a thin viscoelastic orthotropic tube is considered. To take into account viscoelasticity of the tube the linear viscoelasticity model is used. The computations have shown that taking into account the tube visco-elasticity leads to decrease of the phase velocity and transmission per wavelength.
