“…[34] Mainly focusing on experimentals, Rohatgi et al suggested a mathematical model that can predict many characteristic properties such as the peak stress, the plateau stress, the densification strain, and the composite density of ceramic hollow sphere filled MMSFs subjected to free (unconstrained) compression. [51,53] The results proved excellent agreement to the experimental data gathered from the literature. [52] The compressive strength can be calculated by Equation 6.…”

“…[35] The filler material (or reinforcement in the composite technologist point of view) is usually built up from oxide ceramics or from iron based metals (steels). [3,6,13,36,37] In the group of ceramics, most commonly 'fly-ash' [22,[38][39][40][41][42][43][44][45][46][47][48][49] (in some cases surface treated fly-ash [29] ), alumina, [50][51][52][53][54] or silicon carbide [4,[52][53][54] are applied. Fly-ash is a byproduct of coal power plants, they are quite cheap and available in large quantities, however their chemical composition can significantly vary and the scatter in their diameter is relatively high.…”

Metal matrix syntactic foams (MMSFs, often referred as composite metal foams (CMFs)) are lightweight materials with high specific strength. MMSFs are on the borderline between metal matrix composites and metal foams. On one hand MMSFs are composites, because they are filled by hollow particles and the particles may add strength to the material. On the other hand, they are foams, because the hollow particles ensure porosity to the material. Among metallic foams, MMSFs exhibit outstanding specific mechanical properties due to the hollow inclusions that are typically made from ceramics or high strength alloys, therefore they can be applied as structural materials. The goal of this paper is to summarize the available data on the mechanical properties of MMSFs with aluminum matrix in order to give a strong support to the design engineers. Since the foams are most frequently loaded in compression, the main part of this paper is organized around the available standard related to the compressive properties of porous materials and metallic foams. The quasi-static results are complemented by properties measured at higher strain rates. Besides this, some insight into the basic fatigue properties as well as into the toughness of MMSFs is also provided.
