-
摘要: 给出了一族轴对称问题的改进Wilson元,利用强分片检验证明了其收敛性,讨论了单元函数结构.从而给出了一种构造收敛的轴对称非协调元方法.Abstract: A class of modified Wilson arbitrary quadrilateral nonconforming elements for an axisynmetrie problem is proposed.Their convergence is proven by means of the strong patch test.The structure of this finite element class is investigated,Thus a general method of axisymmetrie nonconforming elements with convergence properties is presented.
