Abstract
In this framing study, we propose a new lunar-habitat design based on topological interlocking of the building blocks. The design combines block geometries that permit interlocking without binders or connectors with a pyramidal overall structure. This approach is well suited for ISRU-enabled extraterrestrial construction. Finite element simulations employing the Drucker-Prager model confirm that habitats manufactured from lunar regolith using this concept are tolerant to local failures or missing blocks. We further suggest that this approach can be extended and improved by optimising the geometry of the interlockable building blocks.
