Abstract Scope |
This study investigates the brittle tensile deformation behavior of carbon foam to determine other damage mechanisms that lead up to the brittle failure. CFOAM22 will be used as the carbon foam to create modified dogbone specimens for tensile loading, and thin hourglass samples for tensile damage detection. Damage detection will be analyzed through the use of Acoustic Emission (AE) for damage initiation alongside a Keyence microscope for visual inspection in the hourglass samples. In addition, computed tomography (CT) scans were obtained of the CFOAM22 for an accurate recreation of the real structure. The CT scans will be used for a Finite Element Analysis (FEA) model to recreate the tensile deformation mechanisms. The models were run in ABAQUS with the explicit step solver to determine non-linear solutions that were validated with experimental results. |
