dc.description.abstractLightweight sacrificial energy absorbing structures are widely used in defence, automotive industries to protect occupant’s lives and critical infrastructures in the event of high-speed impact. This thesis proposed two novel design strategies to address the energy absorption ability of thin-walled metallic tubes. First, the surface of the tubes was locally strengthened using buckling-guided hardening treatments to both control their deformation and increase energy absorption. Secondly, the tubes were filled with PEKK honeycomb cores, bioinspired from the spider web design, demonstrating further enhancement with tailorable energy absorption capacity, while retaining their lightweight features. The findings suggest that the proposed strategies would complement the design of next generation lightweight, high performance energy absorbing structures for crashworthiness applications.
