Sumario:It is presented a mixed solution for solving the behavior of multilayer plates by the method of finite elements. The main purpose is to consider each layer as if it were an isolated plate, where the continuity of displacement is achieved by Lagran ge multipliers (which represent static variables). This procedure allows us to work with any model for single plate (so as to ensure the proper behavior of each layer) and multilayer system complexity is avoided by ensuring the condition of displacement by the Lagrange multipliers (static variables). The plate is discretized by a finite element modeling based on a primary hybrid model, where the domain is divided by quadrilaterals, both to the field of displacement and to the static variable. We also use mathematic oriented computer programs which have internal functions for numerically solving systems of linear equations, eigenvalues, and so on. This hybrid or mixed element plate was implemented and several examples were calculated that have been verified successfully for results obtained by other literature methods.
