“…C-shape bending is observed in some of the struts of specimens with compression strains of 29.8% and 49.5%, e.g., region 13, 24 and 26 ( Figure 8b). Plastic S-shape and C-shape deformation in some struts of open cell aluminum alloy (A356) and 316L stainless steel foams under quasi-static compression has been observed in the previous works by others [26,27]. Deformation bands are present in a few struts of the specimen with the highest level of compression strain (49.5%).…”

“…As stated in [29], in most cases, mechanical properties of metal foams do not depend on cell size. This was observed in the study of the deformation behavior of the open-cell stainless steel conducted by Kaya and Fleck [27], wherein, at the same relative density, the inhomogeneity in the microstructure was found the influential factor and not the cell size. Investigating the influence of density, cell size and cell shape on the mechanical properties of open cell 6101 aluminum foams, Nieh et al [31] found that, under similar densities, cell size does not have any significant effect on strength while the cell shape had some influences [31].…”

“…However, given that many of the struts are inclined to the loading axis, it is expected that buckling partially contributes to many of the strut deformatins. In Kaya and Fleck's work [27], both bending and buckling were addressed as two different deformation mechanisms appeared in different struts. In Daxner's work [41], both buckling and bending are pointed out as "dominating deformation mechanism" in the struts of "open-cell metallic foams".…”

Biodegradable metal foams have been studied as potential materials for bone scaffolds. Their mechanical properties largely depend on the relative density and micro-structural geometry. In this work, mechanical behavior of iron foams with different cell sizes was investigated under various compression tests in dry and wet conditions and after subjected to degradation in Hanks' solution. Statistical analysis was performed using hypothesis and non-parametric tests. The deformation behavior of the foams under compression was also evaluated. Results show that the mechanical properties of the foams under dry compression tests had a "V-type" variation, which is explained as a function of different geometrical properties by using a simple tabular method. The wet environment did not change the compression behavior of the iron foams significantly while degradation decreased the elastic modulus, yield and compression strengths and the energy absorbability of the specimens. The deformation of open cell iron foams under compression is viewed as a complex phenomenon which could be the product of multiple mechanism such as bending, buckling and torsion.

“…Therefore, it is essential to model accurately the multiaxial failure behavior of the metallic foams under impact loading conditions, especially combined shear-compression which is the most realistic loading mode. The previous researches involving the dynamic mechanical property of the foams have been mostly limited to the uniaxial mechanical behavior, such as uniaxial failure strength, the plateau stress, the densification behavior and the energy absorption capacity (Zhao, 1997;Deshpande and Fleck, 2000b;Zhou et al, 2004a;Zhou et al, 2004b;Demiray et al, 2006; Latin American Journal of Solids and Structures 13 (2016) 665-689 Doyoyo and Mohr., 2006;Yu et al, 2006;Peroni et al, 2008;Peroni et al, 2012;Zhou et al, 2012aZhou et al, , 2012bZhou et al, , 2014Hangai et al, 2013;Pichler and Lackner, R.,Duarte et al, 2014;Kaya and Fleck, 2014;Li et al, 2014;Alvandi-Tabrizi et al, 2015;Storm et al, 2015;Vesenjak et al, 2016). But experimental investigations of metallic foams under dynamic multiaxial loading condition are not available by now.…”

A series of dynamic tests were conducted on a closed-cell aluminum alloy foams in order to determine experimental failure surface under impact loading conditions. Quasi-static tests have also been performed to investigate failure mechanism under different stress paths. Three typical types of deformation modes can be observed, which corresponds to the different failure mechanism. The failure loci of the foam in principal stress plane are explored from quasistatic to dynamic loading conditions. A significant strength enhancement is identified experimentally. The expansion of the failure locus from the quasi-static to the dynamic test is almost isotropic. A modified failure criterion for the metallic foam is proposed to predict failure locus as a function of strain rate. This rate-dependence failure criterion is capable of giving a good description of the biaxial failure stresses over a wide range of the strain rates.

“…Solid state processing methods involve the use of metal powders and are especially preferred when the alloy of the foam (e.g., Ni) to be produced has a high melting temperature [1]. Among the solid state processing methods, the slurry coating technique can produce open-cell metal foams with the lowest relative densities [2][3][4][5][6]. In this method, an open-cell polymeric sacrificial template is first coated with the metal slurry.…”

Open-cell nickel-based alloy foams are attractive materials for applications such as sound damping and heat exchange, especially those involving exposure to high temperature environments. This study demonstrated the potential of a developed slurry coating technique for manufacturing open-cell Inconel alloy foams, and then investigated the effect of slurry composition on the microstructure and mechanical properties of the foams. It was found that the compressive properties of the foam can be quantitatively related to its relative density using the empirical equations. The deformation behaviour of the foam is bending-dominated; and unit cell struts undergo brittle fracture after the elastic region. Increasing the slurry solid loading leads to a higher average bulk foam density and more non-uniform crush bands in the foam under compression. Compared to other fabrication processes, this slurry coating technique is able to to produce open-cell Inconel foams with relatively higher strength-to-weight ratios. This study also revealed that the sound absorption capability of the foam increases when its unit cell size is reduced.
