An axisymmetric bending analysis of four-parameter functionally graded annular plate under uniform transverse load is studied. Generalization of four-parameter power-law distribution presented in literature is proposed. Four kinds of material profiles through the functionally graded annular plate thickness are illustrated by varying the four parameters of power-law distribution. Generalized differential quadrature (GDQ) method is used to discretize the system of governing equations. The
