Oscillation of Plates and Shells
This chapter explains the theoretical and experimental determination of the fundamental frequency of free oscillations (vibrations) of cantilever plates. The difference in theoretical and experimental determination of frequencies can be even smaller if a person determines the frequency by the Galerkin method, taking into account the highest approximations. The chapter also explains the investigation of oscillations (vibrations) of both closed and open spherical shells. The method of integral transformation is especially effective with the solution of the multidimensional and dynamic problems; therefore, it is reasonable to expect that spectral method of boundary elements (SMBE) also can be successfully applied to dynamic calculation of structures. As an example of the application of the SMBE to dynamic problems, the chapter considers the oscillations of a plate of an arbitrary form, which lies on the elastic Winklerian base, and which is under the action of a load q(x, y, t).
