Abstract:

It has been proved by the authors that the (extended) Sadowsky functional can be deduced as the $\Gamma$-limit of the Kirchhoff energy on a rectangular strip, as the width of the strip tends to 0. In this paper we show that this $\Gamma$-convergence result is stable when affine boundary conditions are prescribed on the short sides of the strip. These boundary conditions include those corresponding to a Möbius band. This provides a rigorous justification of the original formal argument by Sadowsky about determining the equilibrium shape of a free-standing Möbius strip.
