| Abstract: | A nonconforming finite element method is given for handling of biharmonic equation with non-zero boundary value. This new method is prived to be convergent, and identical with conforming element in accuracy and conldition number. A triangular element with ten degrees of freedom is specifi- cally constructed by applying this method and its error estimate is given. |
