Abstract Scope |
Porous network materials are challenging to model due to their inherent complexity and randomness. The recently developed Kentucky Random Structures Toolkit (KRaSTk) implements a high-throughput approach to generate and compute properties of model representative volume elements (mRVEs) based on physics-based geometric seed descriptions capturing relevant structural complexity. Using this toolkit we have computed bulk effective properties, and distribution of length-scale dependent local properties, of porous network structures as a function of aspect ratio of connecting ligaments. Results suggest that changes in aspect ratio of ligaments do affect the stiffness of the material, but this effect cannot be separated from changes in the reduced density of the porous material. These results demonstrate the potential of the KRaSTk approach for exploring structure-property relationships of complex, randomly-structured materials. |
