Abstract Scope |
Porous materials exhibit stochastic microstructures spanning multiple length scales making it difficult to accurately predict their mechanical properties and deformation behavior. Current work relating microstructural characteristics to macroscale mechanical response has focused on post-mortem SEM imaging. To improve upon these analyses combining micro-computed tomography (micro-CT) with in-situ compression can enable direct correlation between the macroscale mechanical properties and the microscale deformation mechanisms in real time. To this end, micro-CT will be utilized to obtain quantitative 3D information about the deformation of a porous carbon fiber material at the fiber contact and individual fiber level at various levels of macroscale deformation. Simultaneous acquisition of 2D digital image correlation (DIC) data will also occur to provide further visualization and quantification of the operative deformation mechanisms at the mesoscale. These results will provide specific experimental data to tie the deformation behavior across length scales for these materials to specific macroscale mechanical response phenomena. |
