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.

Key words: finite element, nonconforming element, axisymmetric, convergence
