摘要
改进的基于径向基函数的强形式的无单元法(improved radial-basis-function strong-form meshless method,简称IRBFS)是真正意义上的无网格方法,介绍基本原理,求解弹性平面问题,验证了径向基函数的自由参数的最佳取值公式和稀疏化规律的适用性.
Improved radial-basis-function strong-form meshless method (IRBFS) is a truly meshless method. In this paper, the basic principle of IRBFS is introduced, and 2D elastic problems are solved, and the applicability of free parameters' optimal value formula in the radial basis functions and sparse rules are verified.
