“…The responses of empty and foam-filled conical tubes under oblique loads were also investigated by Qi and Yang [16] and the empty tubes was reported to outperform foamfilled tubes in terms of specific energy absorption (SEA). Recently, multi-cells were found to be a type of highly efficient energy absorbers [17][18][19][20][21][22][23][24][25] and Qi et al [26] conducted numerical analysis and multi-objective optimization of tapered multi-cell square tubes under oblique loading. The tapered multi-cells were reported to show the best crashworthiness performance when compared to tapered single-cell, straight single-cell or multi-cell tubes.…”

In this research, a hexagonal honeycomb core under a compressional load is studied numerically from the initial elastic regime to the fully crushed state using the Abaqus finite-element modelling. Two modelling approaches, i.e., a static analysis and an explicit non-linear analysis are applied to a 3D model of an aluminium honeycomb core. This honeycomb structure is compressed quasi statically using rigid plates and displacement control. Moreover, the crushing of the honeycomb-core structure and the failure due to buckling are verified numerically, and a study is also performed to show how different densities, cell sizes and specimen sizes can affect the average crush force and plateau force. A comparison between experimental and numerical results is drawn, showing that the numerical models can effectively predict the mean crushing force and mechanical behaviour with a good accuracy.Avtorji so raziskovali obna{anje jedra heksagonalnega satovja pod tla~no obremenitvijo. Numeri~na {tudija, izvedena s pomo~jo metode kon~nih elementov na programskem orodju Abaqus, je potekala od za~etnega elasti~nega re`ima do popolne poru{itve strukture. Uporabili so dva pristopa k modeliranju, to je: stati~no analizo in eksplicitno nelinearno analizo 3D modela jedra satovja iz izbrane Al zlitine (AlMg3). Izbrana struktura v obliki satovja je bila kvazi-stati~no tla~no obremenjena z uporabo togih plo{~v re`imu kontrole pomika. Nadalje so avtorji numeri~no verificirali poru{itev strukture zaradi njene deformacije. Numeri~na {tudija je tudi pokazala, kako razlike v gostoti, velikosti celic in velikosti same strukture vplivajo na povpre~no in maksimalno obremenitev, ki sta potrebni za njeno poru{itev. Izvedli so primerjavo med eksperimentalno dobljenimi rezultati in rezultati numeri~nih simulacij. Izkazalo se je, da se dobljeni rezultati med seboj dobro ujemajo ter da lahko numeri~ni model dokaj natan~no napove povpre~no obremenitev, potrebno za poru{itev dane strukture. Klju~ne besede: sendvi~struktura, jedro satovja iz Al zlitine, tla~na obremenitev, deformacije, poru{itev, numeri~na analiza na osnovi metode kon~nih elementov UDK 620.1:669.715:620.173

“…Wilbert et al [26] presented a comprehensive study of the compressive response of hexagonal honeycombs through experiments and simulations. More recently, Zhang et al [27] performed simulations and experiments to evaluate the influences of cell number and central angle on the out-of-plane compressive resistance of aluminum honeycombs.…”
