Introduction The analysis of functionally graded materials has become a subject of increasing importance motivated by a number of potential benefits from the use of such novel materials in a wide range of modern technological practices.
As it is reported in the literature [6, 7], the graded materials are rarely isotropic because of the nature of techniques used in fabricating them.
