3D ANALYSIS OF FUNCTIONALLY GRADED PLATES WITH ONE PAIR OF OPPOSITE EDGES SIMPLY SUPPORTED USING HYBRID DIFFERENTIAL QUADRATURE METHOD

摘要：

Three-dimensional analyses of functionally graded plates under arbitrary loads are studied using hybrid differential quadrature method.The plates in consideration have simply-supported conditions at one pair of opposite edges and arbitrary boundary conditions at the other two edges.In the longitudinal direction of plate with two edges arbitrarily supported,the wavelet-based differential quadrature method (WDQM) is proposed to overcome the shortage of generalized differential quadrature method (GDQM) in treating concentrated load.GDQM is employed in the thickness direction for its higher computational efficiency,while at one pair of opposite edges that is simply supported the trigonometric functions expansion is used to satisfy the boundary conditions precisely.Numerical results show that hybrid DQM has high computational efficiency and accuracy under arbitrary load.
