In this article, nite elements are developed on the basis of the displacements and the Pian and Tong functionals with help of Lagrange multipliers. These elements represent sandwich structure in an accurate way, especially at interfaces, where the equilibrium state is satisfied. Developed elements are assessed and compared on several examples of static linear problems.
