    Shapes of Miura Mesh Mechanism With Mobility One
    (Multi-Science Publishing Co. Ltd, 2013) Beatini, Valentina; Korkmaz, Koray
    The Miura Ori is a mechanism composed by a polyhedral deployable surface. It has favorable qualities from engineering prospective that lead the growing interest on it. The present work focuses on its transmission of motion. The mechanism can be represented by spherical 4 bar linkages, and on this account a simple and effective mobility formula is presented. The mechanism having a number of excessive rigid members, it is also possible to remove all or some of them, variously arranged. The changes are included in the calculation of allowable mobility of the system. The resulting tool can be directly used for the design of deployable Miura Ori surfaces with customized shape.

    Cable-Stiffened Foldable Elastica for Movable Structures
    (Elsevier Ltd., 2013) Beatini, Valentina; Royer-Carfagni, Gianni
    A structural element is proposed, made of a row of rigid voussoirs joined by a passing through cable. When the cable is tensioned, the ensemble acquires stiffness and, for appropriate contact profiles of the voussoirs, the response of the element under applied loads is governed by the same equations of Euler's elastica or, in equivalent terms, of a non-linear spline. Releasing the connecting cable, the structure is loosened and can be closely packed. With this system one can reproduce, at least in principle, any desired profile in the "stiff" configuration, and construct free form foldable surfaces of any shape.
