摘要：

To investigate and visualize extremely fast transient dynamic fracture phenomena, the authors and coworkers have developed an experimental system together with an ultra-high speed camera system, synchronized laser systems, and various trigger systems. This paper presents the highspeed photography system, and experimental results for (i) mixed-mode impact fracture, (ii) impact interfacial fracture, and (iii) dynamic branching fracture. For each dynamic fracture phenomenon, a series of high-speed photographs, dynamic fracture histories, variations of fracture parameters such as the dynamic J integral and dynamic stress intensity factors are presented. Governing mechanisms of such dynamic fracture phenomena are also presented.
