A Review Thin-Wall-Tube Energy-Absorbing Structure : Crash-Box

Abstract The sudden impact during a collision of an automobile may cost the life passengers. Several researchers are working to design materials and structures which can absorb impact-energy before passing it One such solution is crash-box-structure placed primarily on frontal side, in-between bumper main part automobile. crash-box-structure’s ability energy influenced by its deformation-properties. Both, shape material will decide how affects it’s deformation. various geometries crash-box’s deformation characteristics discussed in this article. Moreover, use fiber-reinforced composites crash-box also discussed. surface modification affect behavior, review.
