The Lawrence Livermore National Laboratory (LLNL) electric gun is in use for a variety of shock-wave studies using plastic flyer impact on simple materials such as 6061-T6 Al and selected composite combinations at both normal and oblique incidence. The most commonly used flyer is 0.3-mm-thick Kapton at velocities from 1 to 18 mm/..mu..s. The experimentally measured wave shapes and attenuation are compared to code calculations, with particular interest in spall threshold and coupled momentum.
