Totimorphic structures for space application

Abstract. We propose to use a recently introduced Totimorphic metamaterial for constructing morphable space structures. As a first step to investigate the feasibility of this concept, we present a method for morphing such structures autonomously between different shapes using physically plausible actuations. The presented method is part of a currently developed Python library bundling non-rigid morphing and finite element analysis code, which will be made publicly available in the future. With this work, we aim to lay a foundation for exploring a promising and novel class of multi-functional, reconfigurable space structures.
