An asymptotic model of laminated plates
Keywords:
laminate, asymptotic development, finite elementAbstract
This modei of laminated plate has been developed for approximating the full threedimensional stress tensor within the structure. In order to link the three-dimensional displacements and stresses to the displacements of the middle surface, the herein described technique consists in performing and asymptotic development of the solution fields with respect to the half-thickness of the plate. The construction of the complete asymptotic development, giving the possibility to choose the degree of the approximation of the solution, together with the very few restrictive assumptions required by this method enable the study of a very large panel of plates. The model is validated by comparison with an experiment, and also against other finite element models and an analytical solution.
