Free Vibration Analysis of Moderately Thick Antisymmetric Angle-Ply Laminated Rectangular Plates with Elastic Edge Constraints

摘要

A simple formulation for studying the free vibration of shear-deformable antisymmetric angle-ply laminated rectangular plates having translational as well as rotational edge constraints is presented. The aim is to fill the void in the available literature. The spatial discretization of the resulting mathematical model in five field variables is carried out using the two-dimensional Differential Quadrature Method. Validation of the formulation is done with the help of convergence studies with respect to the number of nodes. The results are compared with those from past investigations available only for simpler problems. Effects of material, geometrical, and support parameters are studied.
