Static and dynamic analysis of functionally graded plates using Four-variable refined plate theory by the new function

This study presents the analytical solutions of static and dynamic analysis of functionally graded plates using Four-variable refined plate theory. The objective of this paper is to develop a model to employ the new function ψ(z) for analysis the static and dynamic of functionally graded plates. The validity of the theory is shown by comparing the present results with those of the classical, the first-order, and the other higher-order theories. The results are in good agreement with solution of Reddy.
