ABSTRACT
Here, we investigate the behavior of the energy of a tape spring as its thickness becomes
smaller and smaller. We consider the case of pure bending, i.e., we impose opposite rotations
at both ends of the device. First, tape springs are introduced and their peculiar mechanical
behavior is explained, and the details of the numerical model are carefully introduced. Then,
a parametric study of the device is conducted for increasing end rotations and decreasing
values of the thickness. Thus, we obtain parametric diagrams of reaction moments, energy
per unit thickness, and energy densities. Finally, energy estimates are obtained.
