A mixed formulation for elastic multilayer plates
Comptes Rendus. Mécanique, Volume 331 (2003) no. 5, pp. 337-342.

A new approach based on a mixed formulation is proposed. The main advantage of such a formulation is that the transverse shear stress continuity is automatically satisfied in a natural way. In order to validate the model, comparisons of the proposed theory to Pagano's exact elasticity solutions are made for a bi-layer and a sandwich plate.

Une nouvelle approche suffisamment précise, basée sur une formulation variationnelle mixte, est présentée. L'avantage d'une telle description est de satisfaire directement la continuité des contraintes de cisaillement transverse aux interfaces. Les résultats du modèle de plaque élastique proposé sont validés pour un bicouche ainsi que pour une plaque sandwich en les comparant aux solutions exactes de Pagano.
