Polar method to design foldable plate structures
(Int. Association for Shell and Spatial Structures, 2015) Beatini, Valentina
The paper considers non-developable foldable plate structures. It presents a design method to approximate any surface made by the translation of a generic curve along a straight line or connected segments. The method achieves a continuous, foldable 3D grid which approximates the target surface along two perpendicular directions. The parameters defining the target surface and the sharpness of the folded plates can be freely set. © 2015 IASS.
Translational method for designing folded plate structures
(Multi-Science Publishing Co. Ltd, 2015) Beatini, Valentina
This paper concerns non-developable folded plate structures. It presents the translational method; a design technique that creates three dimensional non-developable systems that can approximate any surface made by translating a generic curve along another generic curve. The continuous folding process is guaranteed by keeping the value of dihedral angles throughout the structure constant at each phase. Once solved the kinematic constraints, the lengths of sides are opportunely varied to approximate any translational surface. The translational method allows for free setting of the target curvature, the approximation span, and the sharpness of the plates.
