THE DISPLACEMENT FUNCTION OF QUASI-CONFORMING ELEMENT AND ITS NODE ERROR
Based on the strain formulation of the quasi-conforming finite element,displacement finctions are constructed which have definite physical meaning, and a conclusion can be obtained that the coefficients of the constant and the linear strain are uniquely determined, and the quasi-conforming finite element method is convergent to constant strain. There are different methods for constructing the rigid displacement items,and different methods correspond to different order node errors, and this is different fiom ordinary displacement method finite element.
