a Visualization of the normalized effective directional Young’s moduli (\({\mathsf{E}}/{{\mathsf{E}}}_{{\mathsf{s}}}\)) and shear moduli (\({\mathsf{G}}/{{\mathsf{G}}}_{{\mathsf{s}}}\)) along the three primary axes for a sample of 5000 unit-cells. This representation covers the design space for both straight and curved bar unit-cells, highlighting selected examples with extreme mechanical properties. b Normalized stress (\(\sigma /{{\mathsf{E}}}_{{\mathsf{s}}}\)) versus strain (ϵ) curves for unit-cells that exhibit similar linear effective stiffness properties but differ significantly in their nonlinear compressive responses. c Distribution of normalized stress (\(\sigma /{{\mathsf{E}}}_{{\mathsf{s}}}\)) at varying strain (ϵ) levels for the entire dataset, encompassing both straight and curved bar unit-cells.
