Triangular differential quadrature and its application to elastostatic analysis of Reissner plates

The recently proposed triangular differential quadrature method (TDQM) is further elaborated in the paper. Explicit formulae to calculate the weighting coefficients for uniform grid are developed. The TDQM is applied to the elastostatic analysis of Reissner plates. In comparison with other available numerical results, good accuracy and rapid convergence are achieved, indicating that the TDQM has attractive potential as a novel numerical technique.
