Frequency Analysis of Orthotropic Square Plates with Circular Thickness Variations in Two Dimensions

This paper is concerned with vibrational frequency characteristics of orthotropic and non-homogeneous square plate having circular thickness variation in two dimensions along with linear density at clamped is carried out. A two-dimensional parabolic variation is assumed for the temperature distribution across the plate. Rayleigh-Ritz technique is employed to compute the frequency for the first four modes of vibration. Authors have performed the convergence study of modes of frequency for orthotropic square plate The objective of the study is to present numerical data that demonstrate how the vibrational frequencies can be controlled by manipulating the plate parameters of the plate.
