Abstract This homogenized, multilayer sandwich structure has a total bending stiffness. The structure has two external skins each of a material having a modulus, a thickness and a width with contribution to the total moment of inertia. The structure also has a core of a foam material sandwiched between the two external skins, wherein the core has a modulus, a thickness and a width with contribution to the total moment of inertia. The external skins are fixed to the core, the strength of the structure being dependent on the core thickness via cubic power, as well as on the placement of the layers within the structure. Cette structure sandwich homogénéisée à couches multiples présente une rigidité totale à la flexion. La structure présente deux revêtements externes dont chacun est composé d'un matériau ayant un module, une épaisseur et une largeur contribuant au moment total d'inertie. La structure possède également une âme de matériau de mousse insérée entre les deux revêtements externes, l'âme ayant un module, une épaisseur et une largeur contribuant au moment total d'inertie. Les revêtements externes sont fixés à l'âme, la résistance de la structure étant dépendante de l'épaisseur de l'âme par l'entremise de la puissance cubique, ainsi que du placement des couches dans la structure.
