A high speed synchrotron X-ray phase contrast imaging setup (PCI) is integrated with a modified Kolsky bar setup to study the deformation and fracture behavior of materials under high strain rate loading at beam line 32-ID, Advanced Photon Source, Argonne National Laboratory. The synchrotron X-ray imaging technique provides a significant advantage over the traditional optical imaging in terms of ability to observe in-situ sub-surface fracture in materials under dynamic loading. In this study, the dynamic loading is applied on the specimens using a modified miniaturized Kolsky bar apparatus. The resulting deformation and fracture history is recorded using the high speed synchrotron X-ray PCI. The effectiveness of the novel union between these two powerful experimental techniques is demonstrated by a series of dynamic experiments on different material systems, including fracture of particles in a granular system, ligament-bone junction damage, fracture of concrete and other geo-materials, and fiber pull-out from composite materials.
