Embodiment Construction

[0030] As shown in the figure, a node-enhanced lattice structure in this embodiment includes the following steps:

[0031] s1. Prepare a variety of lattice materials with different unit cell poses; in this embodiment, six kinds of lattice materials with octahedral unit cell structures are selected as experimental objects, wherein the length of the rod in the unit cell is 4mm, and the diameter of the rod is 0.4mm , the unit cell symmetry axes of the six kinds of lattice materials have different angles θ with the vertical direction. As the angle θ changes, the structural configuration is periodic, so take the angle θ within a period, and take θ as 0°, The structures of 10°, 20°, 30°, 40° and 45° are used as the research objects, and the geometric structures are shown in Figure 1-6.

[0032] s2. carry out static compression experiment to described lattice material, and obtain corresponding lattice material stress-strain relationship curve from experimental result; Use universal c...
