Blast energy absorptio of recyclable beverage cans

The entire world faces the problem of security for industrial, military and civil engineering structures due to terrorist activities. The failure of the critical load bearing members such as beams, pillars, columns etc., and its debris cause major human casualties. Hence a preventive solution is needed to safeguard the civil engineering structures and to avoid human casualties due to explosion. Out of many proposed solutions, the concept of sacrificial cladding design has attracted more attention in terms of its functionality and predictable behaviour [1, 2]. Any sacrificial structure can have two parts; an outer skin and an inner core. The function of the outer skin is to distribute the blast pressure more uniformly to the inner core and the function of the inner core is to absorb most of the energy from the blast or explosion loading. This study deals with the blast energy absorption characteristics of empty recyclable beverage cans (inner core).
