| Abstract Scope |
Nanoporous metals (np-metals) are a class of functional materials characterized by a bicontinuous network of nanoscale pores and solid ligaments. Their mechanical properties benefit from nanoscale effects, leading to enhanced performance. Despite significant contributions to the understanding their mechanical properties, the influence of topology and crystalline orientation on the plastic anisotropy of np-metals remains largely unexplored. In this contribution, we present a systematic assessment of the effects of topology and crystalline orientation on the plastic response of nanoporous gold under multiaxial loading. We employ a levelled-wave open-source code to generate representative volume elements (RVEs) with varying solid fractions and crystalline orientations. Multiaxial loading simulations are performed by means of a Crystal Plasticity FFT framework. Comparison with polycrystalline realizations and a J2 plasticity model allow to distinguish the contributions of topology and crystallographic orientation to plastic deformation. Finally, our key findings are compared with contributions from other simulation techniques and experiments. |
