摘要 利用逆多元二次径向基函数无网格配点法对Reddy的高阶剪切变形理论进行离散,计算了四边简支承受正弦分布横向载荷复合材料层合板的无量纲应力和最大挠度,分析了节点分布方式和密度对计算结果的影响。数值算例表明:逆多元二次径向基函数在复合材料层合板静力分析方面具有较高的精度。 Higher-order shear deformation theories of Reddy discretized by a mesh-free collocation method based on the inverse multiquadric radial basis function are used to calculate the non-dimensional stress and maximum deflection for simply supported laminated composite plates under sinusoidal transverse load. The influence of node distribution mode and density on the results is analyzed. Through numerical experiments, the high numerical accuracy of the inverse multiquadric radial basis function for static analysis of laminated composite plates is demonstrated.
