Abstract:The quasi-conforming technique has achieved great success in linear and nonlinear field of finite element analysis over past several decades. The formulation of quasi-conforming element is simple and flexible, unifying the conforming and non-conforming finite element method. Different from the traditional finite element method, the strain-displacement equations are weakened as well as the equilibrium equations in quasi-conforming technique. Many excellent quasi-conforming elements have been constructed and applied widely in engineering analysis. In this paper, the formulation of the quasi-conforming element is introduced briefly and the choice of initially assumed displacement/strain and the interpolation functions are discussed. Some recent work of quasi-conforming plate/shell elements are summarized. The research on quasi-conforming technique is an original and fundamental work, which contributes to the development of computational mechanics.
