本文提出了一种基于梯度光顺的Hermite径向点插值方法。采用多项式基增广的径向基函数构造具有重要Delta函数性质的形函数。采用光滑Galerkin弱形式离散控制偏微分方程,通过曲率光滑操作放松连续性要求,获得精确的弯曲解.基于挠度和旋转变量的近似使得所提出的方法在强制本质边界条件方面非常有效。详细研究了基于三角形背景单元创建的不同数目的子平滑域的效果。数值算例表明,该方法即使对极不规则的背景单元也具有很好的稳定性和精度。
A smoothed Hermite radial point interpolation method using gradient smoothing operation is formulated for thin plate analysis. The radial basis functions augmented with polynomial basis are used to construct the shape functions that have the important Delta function property. The smoothed Galerkin weakform is adopted to discretize the governing partial differential equations, and a curvature smoothed operation is developed to relax the continuity requirement and achieve accurate bending solutions. The approximation based on both deflection and rotation variables make the proposed method very effective in enforcing the essential boundary conditions. The effects of different numbers of sub-smoothing-domains created based on the triangular background cell are investigated in detail. A number of numerical examples have been studied and the results show that the present method is very stable and accurate even for extremely irregular background cells.
