This paper investigates dynamic stability of an axially accelerating viscoelastic beam undergoing parametric resonance. The effects of shear deformation and rotary inertia are taken into account by the Timoshenko thick beam theory. The beam material obeys the Kelvin model in which the material time

The dynamic sti!ness matrix of an in"nite Timoshenko beam on viscoelastic foundation in the moving co-ordinate system travelling at a constant velocity is established in this paper. The dynamic sti!ness matrix is essentially a function of the velocity of a moving load applied to the beam system. Thi
Since, especially for higher frequencies, Timoshenko's theory gives more reliable results than EulerβBernoulli's theory, systems of beams, like frames, under arbitrary dynamic excitations should be analyzed on the basis of this refined theory. In this paper, after deriving the basic fundamental solu
The quasi-static and dynamic responses of a linear viscoelastic Timoshenko beam on Winkler foundation are studied numerically by using the hybrid Laplace-Carson and finite element method. In this analysis the field equation for viscoelastic material is used. In the transformed Laplace-Carson space t
