dc.description.abstractIn scope of this study, forced vibration analysis of viscoelastic helical rods with varying cross-section and functionally graded material are investigated. Differential equations governing the dynamic behavior of helical rods are obtained in Laplace domain by the Timoshenko's beam theory. Material and section geometry are assumed to be varying functionally along the rod axis. Viscoelasticity of the material is implemented via Kelvin's model. Stiffness and transfer matrix methods are used together in order to obtain dynamic stiffness matrix of the system. Acquired results in Laplace domain are converted to time domain by using Durbin's inverse Laplace algorithm. A parametric study is carried out for the investigation of the effects of material variation, non-uniformity and damping on the forced vibration of functionally graded viscoelastic rods.
