Nanoporous metals display properties that make them attractive for a variety of technological applications. An adequate assessment of its mechanical properties and deformation mechanisms is a key aspect for the proper use of this material. We report on molecular dynamics simulations of nanoindentation tests for a model polycrystalline nanoporous gold structure comparable to foams produced by dealloying. Hardness, plasticity mechanisms, the extension of the plastic zone and the applicability of several scaling laws are discussed.
