“…It has been observed that the crush strength depends on cell shape (hexagonal cells with different branch angles were studied) [18,19,20,21,22] and wall thickness [23,24,25,26]. The honeycomb structures were investigated with numerical analysis or experimentally in both in-plane [27,28,29,30,31] and out-of-plane directions [20,32,33,34,35,36] to obtain various parameters to provide answers about the mechanisms of failure.…”

Laser Engineered Net Shaping (LENSTM) is currently a promising and developing technique. It allows for shortening the time between the design stage and the manufacturing process. LENS is an alternative to classic metal manufacturing methods, such as casting and plastic working. Moreover, it enables the production of finished spatial structures using different types of metallic powders as starting materials. Using this technology, thin-walled honeycomb structures with four different cell sizes were obtained. The technological parameters of the manufacturing process were selected experimentally, and the initial powder was a spherical Ti6Al4V powder with a particle size of 45–105 µm. The dimensions of the specimens were approximately 40 × 40 × 10 mm, and the wall thickness was approximately 0.7 mm. The geometrical quality and the surface roughness of the manufactured structures were investigated. Due to the high cooling rates occurring during the LENS process, the microstructure for this alloy consists only of the martensitic α’ phase. In order to increase the mechanical parameters, it was necessary to apply post processing heat treatment leading to the creation of a two-phase α + β structure. The main aim of this investigation was to study the energy absorption of additively manufactured regular cellular structures with a honeycomb topology under static and dynamic loading conditions.

“…For example, the out-of-plane compressive strength of aluminium hexagonal honeycomb is 2 times greater than the in-plane compressive strength [11]. Extensive studies on the out-of-plane compressive behaviour of regular honeycombs have been reported in the literature [12][13][14][15][16]. As reported by Radford et al [12], stainless-steel square honeycombs with relative density 0.1   failed with torsional plastic buckling under quasi-static out-of-plane compression.…”

“…Using Kolsky pressure bar testing with a striker velocity up to 300 ms -1 , they found that the dynamic compressive response was governed by three distinct mechanisms: material rate sensitivity, inertial stabilization of the webs against buckling, and plastic wave propagation [12,13]. Tao et al [14] investigated the out-of-plane dynamic behaviour of hexagonal thin-wall aluminium honeycombs using a Split Hopkinson…”

“…Zhang et al investigated the stress-strain behaviour of ZTA/Fe45 composites by numerical simulations and found that the particle-matrix interface properties show the dominant impact for yield limit and peak stress while for the critical strain the particle volume fraction is the main factor [16]. The "Honeycomb Structure" is widely applied in the composite design, owing to its good comprehensive mechanical properties and its perfect structure [17,18]. Du J. studied the ZTA ceramic particle reinforced high chromium cast iron composites (HCCI) with a honeycomb structure obtained by infiltration casting and acquired the best casting process parameters by a finite element calculation [19].…”

Abstract:The abrasive wear resistance of zirconia toughened alumina (ZTA) ceramic particle reinforced high chromium cast iron (HCCI) composites has been systematically investigated using a moving wedge type of apparatus. The results of three-body abrasive wear show that the wear resistance of the composites with honeycomb is three times higher than that of the high chromium cast iron. The wear resistance of the composites with a honeycomb structure is close to that of the layer structure and is higher than that of the HCCI because the honeycomb wall in the cell honeycomb structure is prominent and because the honeycomb core is depressed. The wear mechanisms of the composites are mainly microcutting and fatigue fractures. The honeycomb structure forms a "macrocosmic shadow protection effect" and a "microcosmic shadow protection effect" to protect each composite and to improve the wear resistance of the composites.
