Dates: Thursday 17th + Friday 18th September

As the kick-off workshop for the EPSRC project ‘Designing for the Future: Optimising the structural form of regolith-based monolithic vaults in low-gravity conditions’, the aim is to investigate the behaviour of monolithic adobe structures in low-gravity to design optimal structures.

In support of future space exploration, such structures will act as shielding to protect critical assets (such as robots, fuel tanks and power stations) and future inflatable structures (such as living quarters) from extreme extra-terrestrial environments.

Linear and nonlinear numerical structural modelling and parametric static and dynamic analyses will identify the optimal design approach. The aim is to utilise in-situ resources for construction, so as to minimise the weight on future manned explorations.

There have been much recent and ongoing research on: 1. the mechanical properties of regolith (simulants); 2. the In-situ Resource Utilisation (ISRU) framework; and 3. the advances in 3D printing for extra-terrestrial construction. We believe it is time to combine the breakthroughs made in these fields with structural design strategies developed for engineered structures on Earth, in order to define a multidisciplinary approach towards identifying optimal forms in low-gravity structures, subject to extra-terrestrial dynamic environmental actions.

This workshop will focus on advances in extra-terrestrial structural design covering many aspects of the project:

• ENVIRONMENT: Natural hazards with a particular focus on ground motions (moonquakes and meteor impacts)

• STRUCTURES: Particularly optimising regolith shielding structures

• MATERIALS: Structural materials made out of local regolith following the In-Situ-Resource-Utilisation (ISRU) strategy

• APPLICATIONS: Including ISRU, robotics, 3D printing in extreme conditions, and more.
