The element is a six nodes C* triangular element based on a new kind of kinematics and built from Argyris interpolation for bending, and Ganev interpolation for membrane displacements and transverse shear rotations. This kinematics allows to exactly ensure both, the continuity conditions for displacements and trans- verse shear stresses at the interfaces between layers of a laminated structure and, the boundary conditions at the upper and lower surfaces of the plates. The representation of the transverse shear strains by cosine functions allows
