Abstract

In this paper, the crush behaviour, crushing efficiency, absolute energy absorption, specific energy absorption and peak load of rectangular tubes made of aluminium alloy 6063 of Paper honeycomb filled and aluminium honeycomb filled subjected to quasi-static compressive loading have been numerically and experimentally investigated. Effect of changing the filler material inside the tube on the specific energy absorption characteristics has been evaluated. Model parameters were determined from quasi-static compression test on paper honeycomb and aluminium honeycomb structure. Peak load carrying capacity, mean crush force capacity of aluminium honeycomb filled aluminium alloy 6063 boxes was higher. Specific energy absorption of paper honeycomb crash box was higher than aluminium honeycomb crash box. The experiments regarding crushing behaviour of crash boxes were conducted on compression test machine whereas numerical simulation was performed through commercially available finite element analysis solver LS-DYNA 971. With the addition of softer filler material increase in energy absorption capacity was observed which is useful in crashworthiness application.
