Benchmark solution ===================== Calculation method used for the reference solution -------------------------------------------------------- The reference solution is obtained by solving the reference problem by considering only mechanical behavior. Benchmark results ---------------------- We will focus on the values of the stresses :math:`{\sigma }_{\mathit{xx}}` and :math:`{\sigma }_{\mathit{xy}}`, and the total deformations :math:`{\epsilon }_{\mathit{xx}}`, :math:`{\epsilon }_{\mathit{yy}}` and :math:`{\epsilon }_{\mathit{xy}}` **.**
