Abstract
A deformable device includes a deformable beam or hinge having an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength in the extended state is greater than a different stiffness and strength in the flattened state, the deformable beam or the hinge deformable along a long axis. An end face cross section transverse to the long axis includes a first periodic curved member which defines at least two shaped curves. A second periodic curved member defines at least two shaped curves. The second periodic curved member is mechanically coupled to the first periodic curved member at respective ends of the end face cross section. The first arc length of the first periodic curved member and the second arc length of the second periodic curved member are of about a same arc length.
