✦ Synopsis

A theoretical model for viscoelastic beams with variable section is derived using the principle of virtual work; a linearization is then obtained and stationary solutions are numerically studied. This allows a brief study of their stability and an interpretation in terms of damping.

In particular an interesting feature of the limit speed is shown, 0 Elsevier, Paris turbines / Timoshenko model for beams I Kelvin-Voigt body I stability of stationary solutions
