For orthotropic plane strain problems, the various existing calculation methods are very complex. The orthotropic plane strain problem with cracks have solved by using a new element model, and compared with the finite element method, it can be found that the displacements and the stresses of the two methods are in good agreement.

The method is extremely simple. With the reduction of the element size, the calculation results are infinitely close to the exact solution.
