“…Renaissance precedents include: Abeille's flat vaults (Figure 1(d)) based on truncated tetrahedral components 16 whereas contemporary applications include doubly-curved spatial structures. [23][24][25] In terms of assessment, these structures can be mortarless and potentially scaffoldless; however, and as discussed in literature, when used for curved geometries multiple different voussoir geometries are necessary. This can hamper the reusability potential since each voussoir is constrained both in terms of global geometry and its location within it.…”

Extra-terrestrial infrastructure design and architecture are experiencing a resurgence due to the prospect of permanent human presence on celestial bodies such as our moon and Mars. There, the conditions and constraints within which structural design and assembly should be developed are extreme – for example, scarcity of processed structural material, labour, machinery and imports from Earth. Consequently, the guiding design principles for building off-Earth should include efficient In-Situ Resource Utilisation (ISRU) and reusability. Significantly, these aspects have striking similarities to some characteristics of our vernacular construction history on Earth, such as inherent material efficiency and use of local materials. The majority of contemporary proposals for off-Earth design concern 3D-printed monolithic structures which are not reusable nor reconfigurable. As a result, there is scope for developing component-based, recyclable infrastructure which is based on efficient ISRU. In this research paper, we propose a two-fold assembly and structural design methodology which synthesises three-dimensional geometries in static equilibrium and vernacular construction techniques for deriving scaffoldless, component-based structures. This framework is underpinned by the development of a bespoke mechanically interlocking system which enables mortarless construction. This minimises the need for importing material binders and maximises the reconfigurability and reusability of off-Earth infrastructure.

Topologically interlocked assemblies have traditionally been explored to study properties such as strength, toughness and fatigue when applied axial compressive load. The interlocked assemblies are used in real-life applications ranging from the aerospace industry to the construction sector. This concept is generally applied to segmented blocks to study what parameters affect failure and how the failure occurs. The Segmented interlocked assemblies are investigated to optimize performance and weight compared to a monolithic design with poor strength characteristics. Strength to weight ratio is beneficial to applications where the efficiency of the product relies heavily on the weight. This study is performed on the 3D printed cubes with interlocking geometric slots, and the segmented cubes were investigated for failure through a three-point bending test under different conditions. The study used parameters such as speed of testing, lubrication between blocks, and the shape of the slots. This paper makes use of the Taguchi design of experiments in combination with grey relational analysis to optimize the parameters. Different lubrications were used to create a variation in friction between the blocks simply. After processing the data, it was concluded that the best condition was a circle shape, with lubrication #1 at an indenter speed of 10mm/min, followed by a circle and dry at 5mm/min. Triangle shape with lubrication #1 at a speed of 5mm/min was third in terms of the overall rank. According to the results, the worst-performing condition was a circle shape with lubrication #2 at a 1mm/min speed.

“…Historically, interlocking building block systems have been used to construct floors and walls, see discussion in [13,14]. Recent efforts have revived these concepts in the context of a modern stone architecture for the 21st Century [15,16,17,18,19,20]. In the context of engineering material systems, the terminology Topologically Interlocking Material Systems has been introduced [5,21,22,23,24].…”

Topologically interlocking material (TIM) systems are composed of convex polyhedral units placed such that building blocks restrict each other's movement. Here, TIM tubes are considered as rolled monolayers of such assemblies. The deformation response of these assembled tubes under diametrical loading is considered. This investigation employs experiments on additivelymanufactured physical realizations and finite element analysis with contact interactions. The internal load transfer in topologically interlocking tubes is rationalized through inspection of the distribution of minimum principalstress. A thrust-line (TL) model for the deformation of topologically interlocking tubes is established. The model approximates the deformation response of the assembled tubes as the response of a collection of Misestrusses aligned with paths of maximum load transfer in the system. The predictions obtained with the TL-model are in good agreement with results of finite element models. Accounting for sliding between building blocks in theTL-model yields a predicted response more similar to experimental results with additively manufactured tubes.
