Compression and energy absorption characteristics of additively manufactured reticulated tubes filled with spherical reticulated shells under axial crushing

Effects of Different Configurations on Compression Responses of Honeycomb‐Filled Circular Tube via Selective Laser Melting

“…Since they are combinations of nonrigid connections, their performance is not particularly outstanding. Although some components of TSR [ 43 ] are also prepared by SLM, they are limited by the nonintegrated combined structure and therefore have poor performance. Bio‐inspired multicell tube (named UCGS) [ 44 ] also uses the SLM‐integrated molding method, and its performance in specific strength and specific EA has exceeded that of a small number of HFCTs.…”

“…Figure 9 shows the comparison of specific strength and SEA values of HFCTs in this study with the filled structures reported in the literature. [37][38][39][40][41][42][43][44] The rhombic dodecahedron lattice structures, [37] face-centered cubic lattice, [38] and hybrid lattice structure [39] are all SLMed stainless steel lattice structures. However, due to structural design reasons, their EA and specific strength are lower than HFCTs.…”

“…In particular, the specific strength and SEA data of HFCTs under different parameter conditions have a range distribution, so they can be designed and applied according to different application requirements and can replace solid rods in specific fields.

Properties of 3D Double-Arrow Negative Poisson’s Ratio Lattice Structure under Quasi-Static Compression and Low-Speed Impact

“…Wang et al [39] proposed an octagon auxetic reentrant honeycomb structure, quasistatic compression experimental test, and finite element method are conducted obtaining the effects of NPR of the proposed structure, and the results show the new structure has a superior energy absorption capacity than the traditional honeycomb structure. Wu et al [40] combined four spherical reticulated shell structures with thin-walled tubes and reticulated tubes and compared the energy absorption capacity under quasistatic compression and impact status.…”
