“…The solid copper tube which represented the non-sacrificial member was rigidly fixed to a heavy metal panel. The top cover which represents the skin plate of the sacrificial cladding structure was mounted over an empty 5 beverage can. The top surface was completely instrumented with an accelerometer and a pressure sensor to measure the acceleration of the skin plate and the reflected pressure from the top face of the skin plate respectively.…”

This article deals with the experimental and numerical blast study on a single empty recyclable metal beverage cans. The idea is to make a macro-foam (sacrificial cladding structure) out of these cans to protect the main load bearing members of civil engineering structures from the air blast load. Close-range free air blast tests have been conducted to understand the crushing behaviour and the energy absorption of a single empty beverage can in detail. To conduct such an air blast test a special small-scale test set-up was designed and manufactured. The effect of skin plate surface area and its nature on the blast parameters is studied. Furthermore, the effect of inertia of the skin plate on the crushing performance of the beverage can is evaluated. Tests have been conducted with different plates (made of aluminium and sandwich composite materials) with different masses which represented the skin plate of the proposed sacrificial structure. The measured blast parameters from the experimental tests were compared with ConWep predicted data. Furthermore, the influence of the finite surface area of the skin plate on the clearing of the reflected pressure waves was also studied. The deformation behaviour and the corresponding energy absorption of empty beverage cans were captured. During the experimental blast tests it was observed that a part of the total reflected impulse was lost before it transfers to the non-sacrificial structure. Hence, in order to investigate this phenomenon an Eulerian-Lagrangian coupled analyses were conducted using Hydrocodes. The results from these analyses showed that the diffraction and ground reflected pressure wave caused the loss in impulse. The results from the numerical studies have been compared and validated with the experimental results.

“…Generic energy absorption devices which belong to two different categories (type I and II) based on their load-displacement curves were well studied in [5][6][7][8][9][10][11]. The loaddisplacement curve of type I is relatively "flat topped" and for type II the curve falls sharply after the peak crush load.…”

“…In general, such relationships derive from strong simplifications on experimental observation [18][19][20], and their analytical expression is employable directly in numerical models. As consequence of the simplification, the applicability of empirical laws is restricted to a limited range of loading conditions [9,17].…”

“…In such approaches the strain rate dependence is neglected or strongly simplified. In most of the cases, the dynamic conditions induce very high strain rates [6,8], and a scarce experimental literature can be found that deals with intermediate strain rates [9,10].…”

“…However, the effect of strain rate on the deformation mechanisms and the corresponding deformation patterns of the beverage cans have to be further studied and verified for blast loading conditions. Generic energy absorption devices which belong to two different categories (type I and II) based on their load-displacement curves were well studied in [4][5][6][7][8][9][10]. The loaddisplacement curve of type I is relatively "flat topped" and for type II the curve falls sharply after the peak crush load.…”

This paper focuses on the axial impact crushing behaviour of recyclable empty metal beverage cans available in the market. The idea is to make a macro-foam (sacrificial cladding structure) out of these cans to protect the main load bearing members of civil engineering structures from the air blast load. Axial drop weight tests have been conducted to understand the crushing characteristics and the corresponding energy absorption of a single empty beverage can in detail. To conduct such tests a small-scale drop weight test set-up has been designed and manufactured. The deformation mechanisms and the corresponding energy absorption of the beverage cans were studied in detail for different initial impact velocities (1.4 m/s, 2.2 m/s, 3.1 m/s. 3.8 m/s, 4.4 m/s and 4.9 m/s). Furthermore, an analytical model is proposed to calculate the crushing parameters of empty metal beverage cans. The results from the analytical model are compared and validated with the experimental results.
