Improving the crashworthiness of bi-tubular architectures with ABS cores under axial loading: Experimental and numerical investigation

ThanhSon Doan,

et al.

Abstract: In this study, quasi-static axial compression tests were conducted on mild steel bi-tubular architectures with rectangular nested tube (RNT) and square nested tube (SNT) geometries to evaluate their crushing and crashworthiness performance. A multi-criteria decision-making approach was employed to identify the optimal energy-absorbing architecture. The SNT structure, with the smallest gap size between the inner and outer tubes, exhibited the most desirable energy absorption characteristics among the considered… Show more
