摘要
Metallic foams have a combination of properties that make them attractive for a number of engineering applications, including lightweight structural sandwich panels, energy absorption devices, and heat sinks. For many potential applications an understanding of the mechanical behavior of these foams is essential. Recently, there has been substantial progress in identifying the mechanisms of deformation and failure in metallic foams. Here, we summarize the current understanding of the elastic moduli, uniaxial strength, yield criterion, creep, and fatigue of metallic foams.
