| 摘 要： | 本文基于无单元伽辽金法(EFGM)分析了集中载荷作用下弹性地基圆板的弯曲问题。针对问题特征提出了新的节点分布方案和点积分形式，并在此基础上对权函数参数的选取和集中载荷的处理方式作了相关研究。通过算例对比分析，本文方法正确，求解精度满足要求，且与传统无单元法相比计算速度更快。

Rapid Element-free method for circular plate on elastic base subjected to concentrated force |
| |
| Abstract: | This article use the Element-free Galerkin Method to discussed circular plate on elastic base subjected to concentrated force,during which a new kind of node distribution and node integration form were proposed,and on this basis the correlation parameter of the weight function and solution of the concentrated force are also discussed.The results of examples show that the proposed method has high efficiency and accuracy. |
