Abstract
In this work, the buckling analysis of functionally graded materials (FGMs) plates exposed to different load conditions is investigated using an efficient and simple refined plate theory. Uniaxial and biaxial compression loads along with simply supported boundary conditions on rectangular FGM plates are investigated. The effective material properties are computed using the simple power law equation of the volume fraction of the plate constituents. The governing equations are obtained from the principle of virtual works. The accuracy of present analytical solution is confirmed by comparing the present results with those available in existing literature. It can be concluded that the present theory is not only accurate, but also simply in predicting the buckling analysis of functionally graded plates.
