A modal and damping analysis of viscoelastic Timoshenko tubes conveying fluid

This paper presents a viscoelastic nite element approach to the vibration analysis of viscoelastic Timoshenko tubes conveying inviscid incompressible uid, within which the temperature-dependent functions of material properties are assumed known. The derivation of a viscoelastic nite element model, applied to a time-domain solution, is detailed. The dynamic behaviour of viscoelastic tubes conveying uid is investigated for several initial axial tensions and uid velocities. Numerical results are presented and discussed
