| Popis: | Nanoporous materials are characterized by their complex porous morphology illustrated by the presence of a solid network and voids. The fraction of these voids is characterized by the porosity of the structure, which influences the bulk mechanical properties of the material. Most literature on the mechanics of porous materials has focused on the density-dependence of their elastic properties. In addition to porosity, other pore characteristics, namely pore-size and shape described by the pore-size distribution, and pore-wall size and shape, also influence the bulk response of these materials. In this work, the mechanical structure-property relation of nanoporous materials is studied under large deformations using a computational framework. The interdependent microstructural parameters are identified. After a successful correlation between the synthesis and microstructural parameters, the synthesis of porous materials can be guided and optimized by controlling these parameters.
