【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.更多还原

【Abstract】 Elementfree Galerkin method (EFGM) is used to set up the twodimension displacement function in the linear basis and the quadratic basisThe orthogonalization of the basis function is consideredBy using a practical calculation example,the results of EFGM and FEM are compared and the influence of the density of the nodes is studiedAccording to the calculation example,the result is accurate and EFGM is effective 更多还原
