From: Inverse design of cellular structures with the targeted nonlinear mechanical response

(a) Topologies of the unit cell structures generated using cellular automata. A total of 60,000 mesostructures were generated. (b) Finite element (FE) simulation of the generated cellular mesostructures under uniaxial compression. (c) Nominal stress-strain plots extracted from the FE simulation. (d) Principal component analysis (PCA) was applied to the stress-strain data, enabling reduction of dimensionality to 20 principal components.
