“…The panel consists of a core with struts arranged in a pyramidal manner and two faces consisting of a square external frame (with approximate 3.8 · 6.4 mm 2 cross section) filled by a triangular planar array of struts. This architecture is similar to that studied by Zhou et al [5] for a cast Al-alloy LBS panel, with minor modifications to better allow for castability with reactive titanium alloys. The lower right corner of Figure 1(b) shows the structure unit, which consists of three types of struts: (1) short face struts, (2) long face struts (as well as some half-struts connecting to the frame), and (3) core struts.…”

“…Zhou et al [5] reported tests done on both struts and panels cast of an aluminum alloy with major element concentration closest to aluminum alloy 516.1 and 518.0. This panel is similar in design to ours in terms of base configuration, with a similar unit cell architecture, the same strut diameter of 3.2 mm, and a somewhat lower relative density of 13.1 pct.…”

“…[1][2][3][4][5][6] LBSs have been fabricated from various metallic alloys based on aluminum, [1,[5][6][7] copper, [2,5,8,9] and iron. [10][11][12][13] Although titanium alloys are attractive candidates for LBS because of their excellent mechanical properties and corrosion resistance, to the best of our knowledge, only one titanium LBS, fabricated by selective electron beam melting, has been reported in the literature to date.…”

Ti-6Al-4V lattice block structure panels were fabricated using an aerospace-quality investment casting process. Testing in compression, bending, and impact show that high strength, ductility, and energy absorption are achieved for both individual struts and full panels, despite the intricacies involved with casting fine struts (1.6 or 3.2 mm in diameter) from a highly reactive, poor-fluidity liquid titanium alloy. The panel stress-strain curve calculated by finite-element modeling correlates well with experimental results, indicating that the occasional defects, which are common to aerospace grade castings and may be present in the struts and nodes, have little detrimental effect on the overall panel compressive properties.

“…Cells also fail near the base, which shows the need to improve the test to ensure failure in the bulk material. Zhou et al [13] give an analysis of plastic buckling of struts, and show that the critical buckling load, P cr is given by:…”

Open cellular lattice structures, made out of stainless steel, have been manufactured using the micro fabrication procedure of selective laser melting. A single geometry has been considered, namely vertical struts with cross bracing with a cell geometry of a cubic form. Blocks of this material, with dimensions of 25 mm cube, have been tested under compression and shear loading. Three cell sizes have been considered, namely 1.25, 2.5 and 5 mm. Uniaxial compression and shear force versus displacement and failure characteristics of these materials are discussed, In this way, the micro mechanical characteristics of the material and manufacturing parameters are related to bulk properties.

“…Periodic lattice structures exhibit property profiles greatly superior to those demonstrated by the stochastic analogues at the same volume fraction (or weight) [2,3]. Therefore, metal periodic cellular lattice structures can be used to develop light-weight structures that can provide advanced or multifunctional performance for high value engineering products such as automobile, aerospace and medical products [4]. These periodic lattice structures, however, currently face a higher manufacturing complexity and costs than the stochastic structures [2].…”
