摘要
应用无单元伽辽金法建立了二维线性基及二次基下的位移形函数,考虑了对基函数的正交化处理,并应用具体算例将无单元计算结果与有限元结果进行比较,研究了计算结点的疏密对结果的影响等,计算实例表明无单元伽辽金法解决平面问题具有较高的精度.
Elementfree Galerkin method (EFGM) is used to set up the twodimension displacement function in the linear basis and the quadratic basisThe orthogonalization of the basis function is consideredBy using a practical calculation example,the results of EFGM and FEM are compared and the influence of the density of the nodes is studiedAccording to the calculation example,the result is accurate and EFGM is effective
