We study isometric deformations of thin elastic strips of various(Moebius and other)topologies.A centreline-reduced variational formulation gives convenient equilibrium equations in(second-order)Euler-Poincare form.Numerical solutions reveal how closed strips fold into compact shapes with points of stress localisation as the length-to-width ratio of the strip is decreased.Our results may be relevant for determining curvature effects on physical properties of extremely thin two-dimensional structures as for instance produced in nanostructured origami.
