Popis: Recent research in vascular mechanics has addressed deformation and mobile fluid flux in the arterial wall using poroelastic finite element models (FEMs) of undrained and steady-state conditions. However, arteries are subjected to pulsatile pressures and axial tethering. Very little attention has been given to cyclic (pulsatile) arterial wall response. We will use our porohyperelastic (PHE) theory, material properties, and the ABAQUS FE program (Version 5.6) to simulate coupled structural-fluid transport in intact and de-endothelialized rabbit aortas subjected to “normal” as well as “hypertensive” idealized cardiac pressure cycles.
