摘要
We prove interior regularity for W-2,W-2 isometric immersions of surfaces endowed with a smooth Riemannian metric of positive Gauss curvature. We then derive the P-limit of three dimensional nonlinear shells with inhomogeneous energy density, in the bending energy regime. This derivation is incomplete in that it requires an additional technical hypothesis. (C) 2018 Published by Elsevier Masson SAS.
