Abstract

Flexible moulds for production of double curved elements could offer a solution for challenges in realizing freeform architectural design which tends to be costly and time consuming. However developments are still ongoing and promising methods that result in highly accurate elements still remain to be proven. When surfaces are deformed into a specific shape inaccuracies occur easily due to bucking or wrinkling of the surfaces. In this paper a number of concepts are presented which can be used to prevent these effects. The concepts are based on a fundamental relationship between change of Gaussian curvature of surfaces and in-plain strain. Various prototypes that have been made using these concepts will be presented.
