Abstract:
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 formula10-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 mapsformula12 . We show that the formula14 distanceof formula16 from a single rotation matrixis bounded by a multiple of theformula14 distance from the group SO(n) of all rotations.
