The energy functional of nonlinear plate theory is a curvature functional for surfaces firstproposed on physical grounds by G. Kirchhoff in 1850. We show that itarises as a -limit of three-dimensional nonlinear elasticitytheory as the thickness of a plate goes to zero.A key ingredient in the proof is a sharp rigidity estimate for maps . We show that the distanceof from a single rotation matrixis bounded by a multiple of the distance from the group SO(n) of all rotations.
