Materials Testing, 62(5), 471-479.0025-53002195-8572https://www.degruyter.com/document/doi/10.3139/120.111506/htmlhttps://hdl.handle.net/11452/39470In this study, the effects of sections added to multi-cell square tubes on crash performance are examined. Square, hexagonal and circular sections are added to multi-cell square tubes and their results are examined. Finite element analyses under axial loading are performed to examine the crash performance of the multi-cell tubes. Analyses show that by adding a section to the multi-cell square tubes. the crash behavior of the tubes is improved. According to the results, S5H multi-cell square tube reveals the best crash performance. The optimization of S5H is carried out by using genetic algorithms and radial basis functions. The S5H tube presents a good crashworthiness performance and could be used as an energy absorber.eninfo:eu-repo/semantics/closedAccessMaterials scienceCrashworthinessMulti-cellMeta-modellingOptimizationCross-sectionsCrashworthiness optimizationEnergy-absorptionDesignAluminumStrengthColumnsBeamCellsCrashworthinessCytologyGenetic algorithmsAxial loading; ; ; ;;Crash behaviorCrash performanceEnergy absorbersMulticellRadial basis functionsTubes (components)Article0005310338000062-s2.0-85088409456471479625https://doi.org/10.3139/120.111506Materials science, characterization & testingCrashworthiness; Energy Absorption; Tube
