✦ Synopsis

The free vibration analysis of the orthotropic Mindlin plates with edges elastically restrained against rotation has been accomplished using the Rayleigh-Ritz method. Polynomials with properties corresponding to those of the Timoshenko beam functions are introduced as trial functions in the spatial representation of the deflection and rotations of cross sections in two directions of the plates. The results obtained by using polynomials are nearly the same as the Timoshenko beam functions results, but were obtained with considerably less numerical efforts.
