Modelling Of Multistable Shells, A Differential Geometry Based Approach

Shells are thin-walled curved structures that have great potential for multistability. However, there does not yet exist a general model that can be used to predict the stable equilibria of an arbitrary shell; this model would have to capture the complex interplay of (initial) geometry, material parameters and (local) prestress. In this thesis...

3D Printing Concrete on temporary surfaces: The design and fabrication of a concrete shell structure

One of the geometrical restrictions associated with printed paste materials such as concrete, is that material must be self-supporting during printing. In this research paper a new methodology for 3D Printing Concrete onto a temporary freeform surface is presented. This is achieved by setting up a workflow for combining a Flexible Mould...
