Abstract
The vibration analysis of plates using the multivariable spline element method is presented in this paper. The spline functions are applied to construct bending moments, twisting moments and transverse displacement field functions. The spline equations of eigenvalue problems with multiple variables of vibration of plates are derived based on the Hellinger-Reissner mixed variational principle. For simplicity, the boundary conditions which consist of three local spline points are amended to fit any specified boundary conditions. Several numerical solutions of plate vibration analysis are presented which illustrate the accuracy and convergence of the method.
