Abstract
In this paper, free vibration characteristics of stepped rectangular plates have been studied by using the dynamic stiffness method (DSM). The first-order shear deformation theory (FSDT) is used to obtain the governing differential equations of motions. Taking Levy-type plates into account, the displacements and the force boundary conditions are applied at the appropriate edges to develop a dynamic stiffness matrix. The Wittricks–Williams algorithm is used to solve the global dynamic stiffness matrix for computing the plate's natural frequencies with reasonably high accuracy. The complete analysis has been carried out in a computer program using MATLAB. The frequency results using the DSM are compared with the published results wherever possible. Finally, the effect of various plate parameters on the free vibration behavior of various stepped plates has been studied and important results are reported.
