Time Period Analysis of Orthotropic Skew Plate with 2-D Circular Thickness and 1-D Circular Density

In the present study, time period of vibration an orthotropic parallelogram plate with 2 − D (two-dimensional) circular thickness under effect id="M2"> parabolic temperature is investigated for first time. The different edge conditions are id="M3"> C , id="M4"> F id="M5"> id="M6"> S and id="M7"> boundary conditions, where C, S, F stands clamped, simply supported, free edges plate, respectively. variation in density material considered to be id="M8"> 1 (one-dimensional) circular. Rayleigh–Ritz technique used solve differential equation evaluate two modes vibration. A convergence study parallelogram, rectangle square frequency at various also carried out. authors performed a comparative analysis isotropic available published results conditions. main conclusion which we made from this that by choosing above-mentioned parameters, obtained fewer comparison other variations mentioned literature. Also, suggests less variations.
