Figure 8. High-stress distribution in samples with various lattice shapes and sizes: (a) for tetrahedron lattice designs, only stresses exceeding 1000 MPa
are displayed, (b) for hex-vase lattice designs, only stresses exceeding 1000 MPa are displayed, (c) for hex-star lattice designs, only stresses exceeding 1000
MPa are displayed, and (d) for quad-diametral-cross lattice designs, only stresses exceeding 1000 MPa are displayed.
