Abstract

This work attempts at an entirely novel reformulation of Kirchhoff shells using the theory of moving frames which is a powerful alternative method to describe the geometry of smooth manifolds. In this setup, the defining geometrical features of the non-Euclidean manifold co-evolve with deformation, which means that the model is inherently equipped to accurately describe (possibly irreversible) changes in the referential geometry. Insights from the geometrically transparent kinematics as well as an analytical solution reported for thin strips undergoing very large cylindrical bending explicate on the far-reaching implications of the proposed shell model and its possible spin-offs.
