ABSTRACT

Using the theory of Gamma-convergence, we derive from three-dimensional elasticity new one-dimensional models for ribbons exhibiting spontaneous curvature and twist. We apply the models to shape-selection problems for thin films of nematic elastomers with the twist and splay-bend geometries for the nematic director. For the former, we discuss the possibility of helicoid-like shapes as an alternative to spiral ribbons. This is joint work with V. Agostiniani and A. DeSimone.
