| Abstract: | Bilinear curve bounbary triangle element is proposed in this pa- per as the boundary element of curve boundary field.It replaces the commonly used triangle element of straight lines boundary which has a linear displacement modular form in the finite element method the of flat problem.This method improves the computational precision. The integral formulas are given in the paper. |
