| Abstract: | Longitudinal vibration of viscoelastic rod under the action of viscous damper in span is studied. By using the complex theory, the complex characteristic equation is reduced to two simultaneously non linear equations. The effect of the dimensionless viscous damper coefficients, locations of viscous damper in span and the dimensionless relaxation time of the viscoelastic materials on the complex frequencies of longitudinally vibrating viscoelastic rod fixed at one end and free at the other, viscously damped by a single damper in span is analyzed. |
