A note on convergence of low energy critical points of nonlinear elasticity functionals, for thin shells of arbitrary geometry
ESAIM: Control, Optimisation and Calculus of Variations, Volume 17 (2011) no. 2, pp. 493-505.

We prove that the critical points of the 3d nonlinear elasticity functional on shells of small thickness h and around the mid-surface S of arbitrary geometry, converge as h → 0 to the critical points of the von Kármán functional on S, recently proposed in [Lewicka et al., Ann. Scuola Norm. Sup. Pisa Cl. Sci. (to appear)]. This result extends the statement in [Müller and Pakzad, Comm. Part. Differ. Equ. 33 (2008) 1018-1032], derived for the case of plates when S 2 . The convergence holds provided the elastic energies of the 3d deformations scale like h4 and the external body forces scale like h3.
