000014066 520__ $$2eng$$aIn deformable shells conveying pulsatile flow, oscillatory pressure changes cause local movements of the fluid and shell wall, which propagate downstream in the form of a wave. In this study, circular cylindrical shells described by the nonlinear Novozhilov shell theory with flexible boundary conditions conveying pulsatile flow and subjected to pulsatile pressure are investigated considering the pulse-wave propagation. Coupled fluid-structure Lagrange equations for a non-material volume with wave propagation in case of pulsatile flow are developed. The fluid is modeled as a Newtonian pulsatile flow; pulsatile viscous effects are taken into account. In the filture, a more refined model of the one here presented will possibly be applied to reproduce the dynamic behavior of the human aorta and vascular prostheses used for repairing and replacing damaged and diseased thoracic aorta.
