Abstract Scope |
Iron meteorites are thought to be remnants of the cores of differentiated planetesimals, exposed to interplanetary space by collisional events. Since their phases (kamacite and taenite) are unique from the traditional steel phases, it is crucial to understand their material properties and failure mechanisms. In this study, eight specimens are used to characterize the strengths and failure mechanisms of Gibeon meteorite under quasi-static compressive and tensile loading. Although several authors reported Gibeon’s properties under different loading conditions, this paper shows the full-field strain and displacement contours using an in-situ three-dimensional digital image correlation technique that aids in better understating the initiation and propagation of damage surfaces. Further characterization of the post-fracture surfaces will be studied and correlated to the DIC effective strain contours to better study the influence of different phases on the failure mechanisms. These new findings will improve our understanding towards the asteroidal breakup of iron-rich bodies. |
