Abstract. In this work, the nonlinear behaviour of an exponential functionally
graded plate (E-FGP) is studied. The plates are subjected to uniform loads and
their geometric nonlinearity is introduced in the strain–displacement equations
based on Von-Karman assumptions. The material properties of functionally
graded plates are assumed to vary continuously across the thickness of the plate
in accordance with the exponential law distribution; the Hamilton’s principle is
used herein to derive the solution of the system. Several numerical results for
exponential functionally graded plates are given in the form of explicit graphs;
and the effects of material properties on deflections and normal stresses across
the thickness are determined.

1 Introduction
The mechanical properties of the functionally graded materials vary discretely on one
surface to the other. This is achieved by gradually varying the volume fraction of the
constituent materials. the new property functions are adapted and the performance of
materials in harsh environments could be improved.
Several studies of Functionally graded plates on linear thermal bending of FGM
plates are presented such as (Yamanoushi et al. 1990; Koizumi 1993; Tanigawa et al.
1996; Reddy et al. 1999; Praveen et al. 1999; Mizuguchi and Ohnabe 1996).
The response of functionally graded (FG) ceramic-metal plates using a plate finite
element that accounts for the transverse shear strains is analysed by Praveen and Reddy
(1998). Reddy (2000) developed solutions for rectangular FG plates based on the
(TSDT) third-order shear deformation plate theory. A nonlinear cylindrical bending
analysis of FG plates based on the Classical Plate Theory (CPT) has been performed
(Sun and Chin 1988, 1991; Navazi et al. 2006).
