Proceso de formación de los paneles de la fachada mediante plegado curvo con optimización geométrica y mecánica combinada

The generation of 3D surfaces based on curved foldings is a time and cost-efficient process, avoiding the use of moulds. In this paper we demonstrate that by using the mechanical behaviour of materials and folding kinematics we can expand the possibilities of this fabrication technique. Parametric Design is combined with simplified structural analyses of finite element models in order to develop a robust form-finding process and optimise geometries. A non-linear finite element model simulating the step-by-step deformation of the panel from flat to deformed is then used to validate this simplified method. Finally, a series of prototypes at 1:4 scale are built to verify the feasibility of the fabrication pocess in real conditions and the resulting appearance of the finished panel.
