We study the behaviour of thin elastic bodies of fixed cross-section and of height h, with . We show that critical points of the energy functional of nonlinear three-dimensional elasticity converge to critical points of the von Kármán functional, provided that their energy per unit height is bounded by (and that the stored energy density function satisfies a technical growth condition). This extends recent convergence results for absolute minimizers.
