Theoretical arguments about the elastic deformation of frameworks suggest characteristics of mechanically isotropic networks. We explore these concepts on both isotropic and anisotropic networks by manufacturing porous elastomers with three different periodic net geometries. The blocks of patterned elastomers are subjected to a range of mechanical tests to determine the dependence of elastic moduli on geometric and topological parameters. We report results from axial compression experiments, three-dimensional X-ray computed tomography imaging and image-based finite-element simulations of elastic properties of framework-patterned elastomers.17 pageshttp://www.sherpa.ac.uk/romeo/issn/0080-4614/ "...author can archive pre-print (ie pre-refereeing) on preprint servers or websites. author can archive post-print (ie final draft post-refereeing) on author's personal website, institutional website, institutional repository or not-for-profit repository after 12 months embargo.
