Free Vibration Analysis of Ceramic-Metal Functionally Graded rectangular Solar Plates with Porosities Using of HighOrder Shear Theory : Solar Plate FG Composed of (Al/Al2O3) and (Al/ZrO2) Influence by Porosity

This article introduces free vibration study of dynamically graded solar material plates composed and clearly assisted by a mixture of (Al / Al
₂
O
₃
) and (Al / ZrO
₂
) porosity. Defects such as porosity can occur during the manufacture of these plates. The whole action of these plates may be changed. Porosity would be maintained by the thickness orientation of the metal. To determine the equations of motion, the Hamilton principle will be used herein. In this paper, the influence of variance of material properties in terms of the porosity factor on the natural frequencies of solar FG plates is discussed. The effects of aspect ratios, thickness ratio of FG plates and porosity factor are investigated in this analysis on their normal frequencies. It is assumed that for other researchers to analyze their findings, the tabulated findings will be a guideline.
