| Abstract: | This paper gives the boundary integral equations for an orthotropic plane elastic problem and the analytic formulas to evalute the coefficients during the discretization of the constant boundary elements. Numerical examples are given for the calculation of the stress intensity factor of the orthotropic plate. Numerical results in the examples show that the formulas in this paper are correct. |
