主 题：Multilayered plates buckling finite elements interlaminar stresses.
摘 要：It is presented a buckling analysis ofmultilayered plates by the finite elements method with mixed unknowns （displacement and rotations, and transverse interlaminar stresses）. In the mixed model, each layer is analyzed as a single plate, where the continuity of displacement is ensured by Lagrange multipliers which represent static variables. This procedure is easy to be implemented from the computational point of view. A methodology to solve the eigen problem is presented based on the inverse iteration method. The model is verified successfully with results obtained by other authors.
