Abstract:V magistrski nalogi je predstavljena analiza mehanskega obnašanja avksetičnega absorberja trkov. Edinstvena lastnost avksetične strukture je, da imajo negativen Poissonov koeficient. Obravnavani absorberji, z osnovno celico oblike vbočenih šestkotnikov, so bili sestavljeni iz dvanajstih panelov upognjenih pod predpisanimi koti in zlepljeni skupaj v predpisano geometrijo. Obravnavali smo tri absorberje različnih debelin in pa gradiranega, kateri je bil sestavljen iz štirih panelov vseh treh različnih debelin. Z uporabo računalniških simulacij, ob uporabi metode končnih elementov, smo analizirali njihov odziv ob trku. Rezultate simulacij smo nato primerjali z rezultati eksperimentov, da smo validirali simulacijske modele. Iz rezultatov simulacij pa smo nato še izračunali najpomembnejše mehanske karakteristike absorberjev.

Title:Mechanical behaviour analysis of an auxetic crash box
Abstract:The master's thesis presents an analysis of the mechanical behavior of an auxetic crash absorber. A unique feature of auxetic structures is that they have a negative Poisson's ratio. The absorbers observed in the study, had a concave hexagon-shaped base cell and consisted of twelve panels bent at prescribed angles and glued together to the prescribed geometry. The study considered three absorbers of different thicknesses and a graded one, which consisted of four panels of all three different thicknesses. Using computer simulations with the finite element method, we analyzed their collision response. The simulations results were then compared to the experimental results to validate the simulations models. From the results of the simulations, we then also calculated the most important mechanical characteristics of the crash absorbers.
Keywords:auxetic structures, crash absorber, experimental test, computer simulation
