The present work focuses on the development of a theoretical model aimed at relating the mechanical properties of nanoporous metals to the bending response of thick ligaments. The model describes the structure of nanoporous metal foams in terms of an idealized regular lattice of massive cubic nodes and thick ligaments with square cross-sections. Following a general introduction to the subject, ...

Coarsening in three-dimensional polycrystalline systems such as foams, magnetic bubbles, metal crystals, and ceramics is poorly understood because of the absence of data describing the interior of these materials. We introduce magnetic resonance imaging to probe the interior of a foam, providing information on topology and foam drainage. The foam does not appear to coarsen in a self-similar way...

Open-­‐cell aluminum foams represent an important class of core materials that are used to manufacture lightweight sandwich-­‐structured composites. A nickel coa9ng applied by electro-­‐deposi9on can further improve their proper9es. In order to characterize these hybrid metal foams, we perform a full resolu9on computa9on of the microstructure. One of the commonly applied methods to obtain the g...
