碩士 === 國立成功大學 === 造船及船舶機械工程學系 === 87 === The differential quadrature finite difference method (DQFDM) is used to analyze the flexural deflection of composite non-uniform plates . The finite difference operators are derived by the differential quadrature (DQ). They can be obtained by using the weighting coefficients for DQ discretizations. The derivation is straight and easy . By using different order or the same order but different grid differential quadrature discretizations for the same derivative or partial derivative , various finite difference operators for the same differential or partial differential operators can be obtained . Finite difference operators for unequally spaced and irregular grids can also be generated . The derivations of higher order finite difference operators is also easy .
