A non-linear triangular Shell element based on corotational formulation proposed by B. Haugen in his PhD thesis [1] is implemented in the FEM software CARAT++. From the mathematical point of view, the whole formulation is studied including its incorporation with the finite rotation theory and an initial stress extension is provided. The Shell element is put under the test by applying well known benchmarks in order to assure the robustness of the implementation and to observe the capabilities and weak points of the formulation.     «
