We derive a hierarchy of plate models from three dimensional nonlinear elasticity by -convergence. What distinguishes the different limit models is the scaling of the elastic energy per unit volume , where h is the thickness of the plate. This is in turn related to the strength of the applied force . Membrane theory, derived earlier by Le Dret and Raoult, corresponds to , nonlinear bending theory to , Föppl von Kármán theory to , and linearized vK theory to . Intermediate values of lead to certain theories with constraints. A key ingredient in the proof is a generalization to higher derivatives of our rigidity result  that for maps , the distance of from a single rotation is bounded by a multiple of the distance from the set SO(3) of all rotations.
