On considère le problème de minimisation de la compliance d'un matériau élastique soumis à un chargement donné que l'on doit placer dans un domaine dont l'épaisseur tend vers zéro. Nous déterminons le problème limite ainsi que les conditions nécessaires et suffisantes d'optimalité associées.

We consider the variational problems which consist in minimizing the compliance of a prescribed amount of elastic material which is subject to a given load and is placed in a design region of infinitesimal height. We determine the limit problem, and we provide necessary and sufficient optimality conditions.
