Definition
Higher order theory for functionally graded (FG) shells based on the expansion of the 3-D equations of elasticity for functionally graded materials (FGMs) into Fourier series in terms of Legendre’s polynomials. Higher order theory of the axisymmetric shell of revolution. The first order theory of the FG axisymmetric cylindrical plate and spherical shell.
Introduction
In recent years, a new type of composite materials, the so-called FGMs, has been introduced and applied in a wide range of engineering sciences. The FGMs are heterogeneous materials in which the elastic properties change from one surface to the other, gradually and continuously to achieve the required properties. They especially attract attention because of their distinctive material properties, which vary continuously in one (or more) direction(s), in the case of plates and shells usually in the thickness direction (Shen 2009)....
