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