摘要
无单元法的理论基础是滑动最小二乘法,它不需剖分单元,只需结点信息,具有灵活性强,结果精确,收敛速度快等优点。本文对无单元法的基本理论作了概述,并提出无单元法与有限元法耦合的原理,及其研究的现实意义。
The mathematical basis of element free method (EFM) is moving least squares method(MLSM). EFM is a gridless method and requires only nodes. The key advantages of EFM are super flexibility,accurate results,high rates of convergence,and etc. The basic theory of EFM is presented in this paper, fhat is, ta show the question of coupling EFM to FEM(Finite Element Method), which has an realistic meanning.
