Summary of "Exploiting spatial heterogeneity and response characterization in non-uniform architected materials inspired by slime mould growth."

We implement a computational algorithm to study the pattern formation and transition of slime mould. Inspired by shape-shifting feature in growth of slime mould the nutrient-induced, we then translate the learned principles into the design and characterization of cellular materials, with particular focus on the issue of spatial heterogeneity due to the nature of the non-uniform, asymmetric pattern. Guided by clustering analysis, compression tests on 3D-printed samples, and numerical simulations by finite element models, we were able to categorize patterns with certain geometric features (such as layout and symmetry) and found similar mechanical response features, indicating high tailorability of non-uniform architected materials. This study paves the road for the advanced computer-aided design of architected materials and its potential in the development of innovative engineering mechanical devices and structural systems.
