| Abstract: | 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. |

| Keywords: | : isoparametric element formulations: incompatible finite element explicit method/element stiffness matrix |
