摘 要: 本文导出一种等参协调元位移函数的新的表示方法,在此基础上建立起了构造等参非协调元的新方法。作为实例,构造出两个可以给出单刚显式的四结点平面非协调新单元。 A new method to express the displacement field of isoparametric compatible element is presented in this paper, based on it a new method for formulation of incompatible finite elements is developed. Two plane 4-node incompatible elements which can possess explicit element stiffness matrix are constructed as the examples.
