Extended Data Fig. 3

Fracture mechanism maps of the stretch-dominated (a) isotropic compound simple cubic (SC) and body centered-cubic (BCC) truss (b) anisotropic compound SC/BCC truss (c) bend-dominated gyroid and (d) a topology selection map indicating which topology maximizes \(\bar K_{IC}/\varepsilon _f\) in different regions of the \(\bar \rho /\varepsilon _f\) versus \(\bar T\)space.
