Solution to Bending Problem for Functionally Graded Rectangular Plates Using Differential Quadrature Method
摘要
Abstract
Based on the classical theory and first-order shear deformation theory, the linear bending behavior of a functionally graded rectangular plate is studied. The material properties of functionally graded material are assumed to vary continuously through the thickness of the plate, and obey a simple power law of the volume fraction of the constituents. Governing equations for the problem are derived, and then a 2-d DQM is employed to numerically solve the equations. Effects of material constants, aspect ratio on bending of the plate with simply supported boundary conditon are discussed in detail. The results obtained prove that the two-dimensinal differential quadrature method is feasible for the solution to such problem.关键词
