Both models yield a compliance, which is much higher than the predictions of the Gibson-Ashby scaling relation for metal foams and thus confirm the influence of other microstructural features besides the porosity. The linear elastic FEM simulation also yields a substantially stiffer response than the MD simulation, which reveals that nonlinear elastic behavior contributes decisively to the anomalous compliance of nanoporous gold at small structure size.en1359-646220167477Elsevier Sciencehttp://rightsstatements.org/vocab/InC/1.0/Elasticity of nanomaterialsFinite element modelingMolecular dynamicsNanoporousSurface effectsAllgemeines, WissenschaftJournal Articleurn:nbn:de:gbv:830-882.05192910.15480/882.249110.1016/j.scriptamat.2016.11.00610.15480/882.2491Journal Article
