“…The strain rate sensitivity and energy absorption capacity of commercially available metal foams and the correlation between the mechanical response and the physical and geometrical properties have been studied by Montanini [16]. According to Yu et al [17] and Wang et al [18] there are three reasons contributing to the strain rate sensitivity of the cellular structures: (1) cell morphology, (2) cell topology Fig. 1 Open-cell cellular structures without (left) and with (right) the silicon pore filler Fig.…”

Open-cell cellular structures have a high potential for use in automotive, railway, ship and aerospace industry as crash energy absorbers. This paper focuses on the influence of the second phase filler material as a way to further increase the capability of cellular material energy absorption. The behaviour of ductile (aluminium alloy) and brittle (polymer) cellular structures with regular topology with and without the pore filler (silicon rubber) under quasistatic and dynamic compressive loading conditions has been experimentally studied and evaluated. The base material properties of the aluminium alloy and the polymer were obtained with separate experimental testing. The use of second phase filler material resulted in significant changes in cellular material behaviour. It was observed that the pore filler material increases the capability of energy absorption and furthermore improves and stabilises the response of a brittle cellular structures.

“…The strain rate sensitivity and energy absorption capacity of commercially available cellular materials and the correlation between the mechanical response and the physical and geometrical properties have been studied by Montanini [28]. There are four influential parameters contributing to the strain rate sensitivity of the cellular structures: (i) cell morphology, (ii) cell topology, (iii) the micro-inertial effect and (iv) the material strain rate sensitivity [3,14,29,30]. Each contributes to dynamic strengthening of the global behaviour of the foam structure [31,32].…”

“…The number of studies performed considering the effect of strain rate on densification strain is very limited due to difficulty characterisation of the high strain rate response. However, it was observed that, by increasing the strain rate, the densification strain decreases which results in lower capability of energy absorption [19,26,29,30,47]. …”

“…They can amongst others be used as catalyst support [1,2], implant material [3], heat exchanger [4], sound absorber [5] and energy/impact absorbers [6,7,8,9,10,11,12,13]. In the future OCMFs may have the potential to partially replace the relatively heavy bulk metals used in crumple zones of cars as low-weight energy absorbers [14].…”

Open-cell aluminium foams with graded coatings as passively controllable energy absorbers

et al. 2015

Compared to most bulk materials, open-cell aluminium (Al) foams (OCAFs) are light-weight and can absorb a significant amount of energy in compression, e.g. during impact. When coated with nickel (Ni), OCAFs can absorb even more energy, making them more appropriate for impacts at higher velocities than uncoated OCAFs. When Ni-coated OCAFs experience low-velocity impact however, the stopping distance during the impact is small compared to that of uncoated OCAFs and hence, deceleration occurs fast. This exposes devices (and possibly human beings) protected by OCAFs to large internal forces leading to internal damage. An OCAF that combines the properties of uncoated and coated OCAFs can absorb energy during both low-velocity and high-velocity impact scenarios. This contribution introduces two of such OCAFs which are created by partially and gradually coating OCAFs. The general mechanics of the two OCAFs are revealed using experimental and numerical observation methods.
