✦ Synopsis

In this paper an investigation is reported into the natural frequencies and modes of laminated composite plates. The finite element approach in this paper shows a good agreement with the available closed form solutions. Three distinguished features of laminated plates are illustrated and discussed; namely, the directional preference of nodal lines, the shift of order of the first in-plane vibration modes, and the variation of mode shapes due to the stacking angle. The in-plane vibrations are obtained. They have not been reported in the literature before.
