Vibration of angle-ply symmetric laminated composite plates with edges elastically restrained

This paper presents semi-analytical solutions to determine the natural frequencies and the mode shapes of angle-ply laminated plates with edges elastically restrained. The finite strip transition matrix technique is extended to apply to angle-ply laminated plates with edges elastically restrained against rotation and translation. The effect of the edge conditions on the natural frequencies and mode shapes are presented. The convergence and comparison of the results with those available in the literature indicate the accuracy and the validity of the proposed technique. The effects of the elastic restraint parameters on the mode shapes are illustrated in graphic forms.
