Query: Data-driven modelling of scalable spinodoid structures for energy
  absorption   The project aims to explore a novel way to design and produce cellular
materials with good energy absorption and recoverability properties. Spinodoid
structures offer an alternative to engineering structures such as honeycombs
and foam with scalability ensuring microscale benefits are reaped on a larger
scale. Various materials and topologies have been utilised for numerical
modeling and prototyping through additive manufacturing. Each design was
evaluated using finite element modelling. Initial results from numerical models
show anisotropic structures achieving high energy absorption efficiency.
Through data-driven optimisation, results show a peak energy absorption value
of 5.34 $MJ/m^{3}$ for anisotropic columnar structure. A physics-informed
biased grid-search optimisation is faster due to parameters being explored in
parallel. To validate the numerical model, compressive tests on various
prototypes were conducted.
