dc.description.abstractABSTRACT: In this study, in-plane naturalfrequencies of stepped circular beams are presented. The material of the beamis considered to be isotropic, homogeneous and elastic. The effects of sheardeformation and rotary inertia are considered in the necessary assumptions andformulations. The obtained canonical form of governing equations is solvednumerically by the complementary functions method (CFM) in the Laplace domain.To obtain the natural frequencies of the considered structures the Laplaceparameter is replaced with the parameter of free vibration. The 5thorder Runge Kutta (RK5) algorithm is applied to solve the initial-value problembased on the CFM. To examine the in-plane free vibration of Timoshenko beamswith stepped circular cross-section a program is coded in FORTRAN. In order todemonstrate the accuracy of the current scheme, present results are comparedwith those of literature.  The accuracyand efficiency of the presented results are observed.

The 5th order Runge Kutta (RK5) algorithm is applied to solve the initial-value problem based on the CFM.
