Abstract
For the analysis of the shock wave of behavior and velocity, pressure propagating in PMMA, we performed 3 methods. To the first, we performed optical observation of the shock wave by the high-speed camera, captured the phenomenon of propagation of shock wave visually, and calculated the shock wave velocity simultaneously. To the second, the pressure measurement experiment with manganin gauge showed the force of the shock wave. To the third, numerical analysis by LS-DYNA complemented these data. In addition, pressure measurement experiment and numerical analysis data are in agreement comparatively.
