【摘要】 用微分求积法分析层合板的稳定性时，离散节点的选取是计算能否成功的关键。给出了两种节点坐标的计算公式，通过对多种情况的计算，比较了各种节点分布形式所得结果的收敛性及准确性。结果表明，节点离散规律，可得到令人满意的结果。更多还原

【Abstract】 The grid spacing plays an important role in the buckling analysis of composite laminated plates by the Differential Quadrature (DQ) method. Two formulae are proposed to compute the grid spacing and the convergence of the DQ method is then investigated.It is found that the DQ methOd with the proposed grid spacings gives satisfactory resuIts for vari-ous benchmark problems considered in this paper.更多还原
