摘要
根据变分原理，采用罚函数法满足本征边界条件，得到了平板弯曲计算的无网格法控制方程，并应用于弹性板的计算中。算例表明该方法适用性强、精度较高，可以同时适用于薄板和厚板的计算。
The governing equation of meshless method is obtained on the basis of variational principle for which penalty function method is used to enforce the eigen boundary conditions. The presented method is used for calculation of elastic plane-plate. Numerical examples show that the presented method is applicable widely, considerably precious, and can be used for the calculation of both thin and thick plate.
