| Abstract: | A boundary element method of the straight line element by using analytical integration for calculating two-dimensional problems including rotational inertia is developed in the paper. The analytical formulas are derived. The calculation results of an example show that the method introduced in this paper possesses a higher numerical precision, especially in the case that the stresses of the inner points near the boundary are calcalated. |
