Fig. 5: Graded truss lattice materials using a building-block-based method.
From: Inverse design of truss lattice materials with superior buckling resistance
a Gradient of microstructures generated by symmetrically composing two elementary building blocks (from Fig. 1b) with N = 6 finite-length strings. The dashed red line represents the axis of symmetry. b Gradient of microstructures generated by composing two previously inverse-designed unit cells (from Fig. 2e) with N = 6 finite-length strings. A symmetric generation is not here shown for the sake of clarity in the visualization. c Example of gradient smoothness induced by increasing N to 50. A and B represent two different microstructures.
