Effects of supersonic shock waves studied for steel and aluminum.(MILITARY MATERIALS)
Advanced Materials & Processes, October, 2006
When high explosives detonate, they generate supersonic shock waves that can cause materials such as steel and aluminum to deform and ultimately fail. Capturing the details of this dynamic process involves learning how the shock propagates and interacts with materials, and how the material deforms, fails, and fragments, say researchers at Lawrence Livermore National Laboratory, Livermore, Calif.
To study the process, the scientists developed a multi-channel X-ray system called Hydra, which provides a window into the process through detailed radiographs of metals as they respond to detonations and the intense shocks generated. "People usually think of imaging systems as just taking 'pictures,' but Hydra provides much more," says Livermore physicist John...
