AN AXISYMMETRIC BENDING ANALYSIS OF FUNCTIONALLY GRADED ANNULAR PLATE UNDER TRANSVERSE LOAD VIA GENERALIZED DIFFERENTIAL QUADRATURE METHOD

Hamad M.H., F.Tarlochan

Abstract: 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 convergence of the method is illustrated and the validation of the results is done by a comparison with another study which available in the literature and good agreement between two studies was found.
