Deformation behavior of nano-porous polycrystalline silver. Part II: Simulations

Three-dimensional finite element simulations of nano-porous silver structures are performed to understand the correlation between the porous morphology and the mechanical behavior. The nano structures have been obtained from ptychographic X-ray computed tomography. The simulations allow distinguishing between the interplay and role of the ligament size, the pore morphology and the porosity, and therefore provide a better comprehension of the experimental observations. We show that the proposed model has a predictive character for mechanical behavior of nano-porous silver. (C) 2017 Published by Elsevier Ltd on behalf of Acta Materialia Inc.
