The project aims to explore a novel way to design and produce cellularmaterials with good energy absorption and recoverability properties. Spinodoidstructures offer an alternative to engineering structures such as honeycombsand foam with scalability ensuring microscale benefits are reaped on a largerscale. Various materials and topologies have been utilised for numericalmodeling and prototyping through additive manufacturing. Each design wasevaluated using finite element modelling. Initial results from numerical modelsshow anisotropic structures achieving high energy absorption efficiency.Through data-driven optimisation, results show a peak energy absorption valueof 5.34 $MJ/m^{3}$ for anisotropic columnar structure. A physics-informedbiased grid-search optimisation is faster due to parameters being explored inparallel. To validate the numerical model, compressive tests on variousprototypes were conducted.
