In this study, the local fracture behavior and damage state near the crack tip in a particulate composite material were investigated through the use of precracked sheet specimens. The specimens were subjected to a simple incremental strain history at room temperature. During the test, a high-energy real-time X-ray system was used to record the X-ray data and the fracture process near the crack-tip region. The experimental data were analyzed and the results are discussed.
