Static Analysis of Sandwich Plates by Hybrid Finite Elements

Résumé

As sandwich plates become more and more an important structural component, it would be essential to develop analysis tools taking their speci cities into acount. The present work concerns the development of hybrid sandwich nite elements modelling the mechanical behaviour of sandwich plates in shear in a more realistic way, and respecting physical phenomena at the interfaces between the skins and the core which have in general very heterogeneous mechanical properties. These elements are initially composed of three sub-elements in the same manner as the sandwich plate. The hybrid formulation has been retained because it permits to de ne, in a simple way, a modelling corresponding to all required specifications with the minimum number of variables. In the direction of the thickness, stress and displacement elds are both linear in each layer. They both are quadratic in the others directions to take exural e ects into account. We present in this paper several results and comparisons of static linear problems.
