Using dimensionally reduced models for the numerical simulation of thin objects is highly attractive as this reduces the computational work substantially. The case of narrow thin elastic bands is considered and a convergent finite element discretization for the one-dimensional energy functional together with a fully practical, energy-monotone iterative method for computing stationary configurations are devised. Numerical experiments confirm the theoretical findings and illustrate the qualitative behavior of elastic narrow bands.
