摘要：
Mechanics of nanoporous metallic materials have been an interest due to their applications in a wide range of areas such as sensors, energy conversion, and smart materials design. In this study, the effects of morphological parameters, such as ligament diameter and length, on wave propagation in bicontinuous porous nanostructures is studied by using the discontinuous Galerkin method. Computational results show that energy is localized on the surface independent of the morphological parameters. It is observed that localization length increases with the increase in frequency. In addition, surface roughness parameter and ligament diameter do not have a significant influence on localization length.
