Using High-Speed Camera to Investigate Failure Waves in K9 Glass

摘要

The high-speed shadowgraph technique was used in visualization of the shock wave moving, damage formation and development in the glass specimen. It is found that failure wave formed at the shocked surface and inner interface, and propagated into specimen following the shock wave. It is concluded that formation of failure wave was connected with the surface of glass-specimen, and it is a moving fractured front. The work finished here will be helpful to understand the mechanism of failure wave.
