Benchmark solution ===================== Benchmark solution --------------------- The numerical solution obtained with a multi-layer plate theory in orthotropic linear elasticity is given in the reference [:ref:`bib1 `] page 341. Benchmark results ---------------------- At point :math:`C`, we calculate the following displacement :math:`z` of the point as well as the stresses :math:`{\sigma }_{x}` at the lower and upper interfaces of the skins. Uncertainty about the solution --------------------------- Digital solution. Bibliographical references --------------------------- 1. BATOZ and DHATT. Modeling of structures by finite elements.
