In this article, the static and dynamic behaviors of macro and nano inhomogeneous plates made of functionally graded materials (FGMs) have been investigated based on three-dimensional elasticity theory in combination with the nonlocal theory of Eringen. Variation of deflection along the thickness has been considered as the result of three-dimensional analysis. The governing equations have been derived and developed considering the nonlocal theory for nano-scale plates. Conveniently, the results of macro-sized plates were concluded by neglecting the small scale effects. The results were compared with the some related papers available in the literature. Since the three-dimensional elasticity has been applied, the obtained results are more accurate than other plate theories. In addition, if the plate is subjected to thermal loading, only the results of three-dimensional analysis will be correct. Since the nonlocal analysis has been assumed, the small-scale effects and related parameters have been studied for the nano-scale plates. Finally, the effects of some other important parameters have been surveyed on the results, such as the size of plate, loading, FGM parameters, and boundary conditions.
