摘要
本文讨论无单元法的权函数问题,并首次提出在权函数中采用自适应影响半径,以适应结点分布的随机性。实际算例表明,使用自适应影响半径的权函数对求解应力集中或断裂力学问题具有较大的优越性。
This paper deals with the weight function of Element-Free Galerkin Method. A way to incorporate the adaptive influential radius in weight function for adapting the randomness to distributed nodes is proposed. Numerical examples show that a weight function of using adaptive influential radius has advantages to solve the fracture problems or stress concentration problems.
