| Abstract: | Expanding ring experiment is an important method for dynamic fragmentation of solid materials under 1D tensile loading. A liquid-driving experimental technology was developed for conducting expanding ring tests. Using liquid-driven expanding ring device, 1060 aluminum ring was fragmented and the fragments were recovered. Impact deformation of free-flying fragments was avoided through the use of "sample soft-capture" technology. The fragmentation process is observable by modifying the driving direction of the fluid. |
