Low Cost Double Curvature – Exploratory Computational Modelling, FE-analysis and Prototyping of Cold-Bent Glass

The fabrication of projects with complex geometries often implies a significant waste of material, since custom molds need to be created and irregular shapes need to be cut out of larger sized elements. For low curvatures, cold elastic bending processes can be applied. However, elastic bending techn...
