The change in the cross section of a shell with external and internal constraints is analyzed by analytical and numerical methods using simplified nonlinear models. It is shown that an appropriate choice of constraints eliminates unwanted wrinkles and imparts the shape of a regular hollow polyhedron to a circular shell.
