Abstract (EN): A non-linear formulation for general, arbitrary, sandwich shells is presented. The formulation accounts for geometric and material non-linear behaviour of the shell. The first order shear deformation theory is presented as far as the kinematics are concerned. The formulation is implemented in the Ahmad shell element. The formulation is based on the displacement formulation of the finite element method and relies on a five-degree-of-freedom per node. The formulation is discussed, particularly on a cylindrical shell subjected to compressive loads (snapping behaviour).
