Wrinkling of a Stretched Annular Elastic Thin Sheet - Identification of the Optimal Scaling Law for the Ground State Energy

Dr. Peter Bella (MPI Leipzig)

Abstract:
In Bella Kohn: Wrinkles as the result of compressive stresses in an annular thin film, to appear in CPAM] we identified the optimal scaling law of the minimum of the elastic energy of a stretched annular thin elastic sheet. In
this talk I will describe the next step towards the understanding of this problem – I will identify the optimal prefactor in the scaling law. Moreover, I show that this pre-factor can be characterized as a minimum of a much simpler (scalar) variational problem.
