“…Compressive performance of the 3D novel tetrahedral lattice materials compared with those well-known materials. [29][30][31][32][33][34][35] performance and relatively reasonable density than those of other lattice materials. It is worth noting that the novel 3D tetrahedral lattice materials cover a rational density range with prominent strength, which may offer promising applications in various fields.…”

Herein, the compressive mechanical behavior of novel 3D tetrahedral lattice materials is investigated by ways of experimental, numerical, and analytical methods with a good performance of accuracy. Samples with varied length–diameter ratios are fabricated through 3D printing combined with investment casting method. The compressive behavior, deformation characteristic, and energy property of the lattice materials are comprehensively recorded and analyzed with respect to the geometric parameter and compression directions. It is observed that the length–diameter ratio exhibits a significant influence on the mechanical performance and energy absorption of the materials, that is, the lower the length–diameter ratio, the higher the relative density, strength, and energy absorption. Good agreements are observed among the experimental, numerical, and analytical results within a relative acceptable error. Moreover, the mechanical properties and deformation characteristics of lattice materials depend on compression directions to a great extent. In addition, the novel tetrahedral lattice materials with reasonable relative density present superior performance features compared with the other cellular materials.

“…Some studies have been considered two-dimensional topologies of isogrid, 10,11 anisogrid, 10,12,13 and honeycomb 4,14 cores as well as three-dimensional topologies of pyramidal, 6–8,15–20 tetrahedral, 21,22 kagome, 23 X-type, 24,25 octet-truss, 26,27 and corrugated 9,28 cores. Furthermore, the effect of using metal 7,27,29,30 and fiber-reinforced composite (FRC) materials 17–26 on the capability of carrying various loading has been investigated. Examples of these loadings are axial compression, 10–13 in-plane compression, 17,19,25,28,30 and out-of-plane compression 4,16,21–25,27,30 loads as well as on three-point bending, 23,28 torsion, 18 shear loading, 16,…”

In this paper, the mechanical behavior of a carbon fiber composite cylindrical pyramidal lattice structure has been predicted based on initial failure criteria and progressive damage under compressive loading. For this purpose, the three-dimensional Hashin failure criteria with instantaneous and gradual unloading models have been employed by the user subroutine UMAT in ABAQUS/Standard. In the instantaneous and gradual unloading models, progressive damage has been controlled by binary and exponential damage functions, respectively. Besides, to validate finite element models, the results have been compared with the experimental tests. Therefore, a new mold has been designed and manufactured for the experimental test of composite cylindrical pyramidal lattice structures. The new mold allows the use of the maximum inherent strength of the fiber-reinforced composite. The predicted force–displacement curves are in good agreement with the experimental test results. Hence, it is possible to use these FE models in the design of ultra-lightweight structures.
