We show that nonlinear plate theory arises as a Γ-limit of three-dimensional nonlinear elasticity. A key ingredient in the proof is a sharp rigidity estimate for maps v:(0,1) 3 →ℝ 3 . We show that the L2 distance of ∇v from a single rotation is bounded by a multiple of the L2 distance from the set SO(3) of all rotations.

Nous montrons que la théorie non linéaire des plaques émerge comme Γ-limite de la théorie de l'élasticité tridimensionnelle. La démonstration repose sur un résultat de rigidité pour des fonctions v:(0,1) 3 →ℝ 3 . Nous montrons que la distance L2 de ∇v d'une rotation est bornée par un multiple de la distance L2 à l'ensemble SO(3) des rotations.
