Introduction
1.Functionally Graded Material (FGM) belongs to a class of advanced material characterized by variation in properties as the dimension varies.
2.In this paper we first formulated in terms of the usual Airy stress function allowing spatial variation in Young’s modulus.
3.The resulting general equation is lengthy. So we employed some scheme the first one is assume stress function is bi-harmonic,
