Abstract:
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.
