Abstract EN
This paper deals with the in-plane vibration of circular annular disks under combinations of different boundary conditions at the inner and outer edges.
The in-plane free vibration of an elastic and isotropic disk is studied on the basis of the two-dimensional linear plane stress theory of elasticity.
The exact solution of the in-plane equation of equilibrium of annular disk is attainable, in terms of Bessel functions, for uniform boundary conditions.
The frequency equations for different modes can be obtained from the general solutions by applying the appropriate boundary conditions at the inner and outer edges.
The presented frequency equations provide the frequency parameters for the required number of modes for a wide range of radius ratios and Poisson's ratios of annular disks under clamped, free, or flexible boundary conditions.
Simplified forms of frequency equations are presented for solid disks and axisymmetric modes of annular disks.
Frequency parameters are computed and compared with those available in literature.
The frequency equations can be used as a reference to assess the accuracy of approximate methods.
