Homogenization of cellular sandwich panels
Résumé
The Bending-Gradient plate theory originally presented in Lebée and Sab (International Journal of Solids and Structures 48 (2011) 2878-2888) is applied to cellular sandwich panels. This theory is the extension of the Reissner-Mindlin theory to heterogeneous plates. Its application clarifies common assumptions made in sandwich theory. It also enables to define a direct homogenization scheme for deriving the shear forces stiffness of sandwich panels. Finally, the conventional bounds used for estimating sandwich panels stiffnesses are justified.
