Innovative thin-walled structures, bio-inspired by the microstructure of Morpho wings, were proposed as energy absorbing devices in this study. A finite element model, experimentally validated, was used to investigate crush responses and deformation modes 18 multi-layered tubes with different geometrical configurations. The crashworthiness parameters determined for structures compared traditional structures. Furthermore, a multi-criteria decision-making method employed order identify best...
This paper deals with the crashworthiness capability of newly designed bitubal columns different polygonal cross-sections (i.e. triangular, square, hexagonal, octagonal, decagonal and circular) reinforced several inside ribs. A large number finite element analyses were performed on these under axial oblique impact loads using LS-DYNA to find indicators. These studied five size ratios (the perimeter a inner tube b outer tube), namely a/ = 0, 0.25, 0.5, 0.75 1. decision-making method, which in...
This study aims to investigate the effects of draw beads on crashworthiness aluminum tubes under axial quasi-static loading. Based this design philosophy, a total 12 beading tube designs with various configurations were developed. Within each design, effect arrangement bead form performance was also analyzed. A finite element model, validated using experimental tests, used and progressive deformation tubes. results, multi-criteria decision-making method known as Technique Order Preference by...
Auxetic structures, with re-entrant (inverted hexagonal or bow tie) unit cells, have received considerable interest due to their negative Poisson's ratio property that results in superior mechanical properties. This study proposes a simple method create non-homogeneous honeycombs by modifying the size of chevron crosslinks. The various structural designs were conceived changing geometrical dimensions crosslinks, namely length (lcl) and thickness (tcl), while maintaining parameters cell...
