Analysis of Shock Wave Propagating in PMMA

There are a lot of studies related to the shock wave which generated by explosive, for example, explosive compaction, explosive cladding, and explosive forming. It is necessary and indispensable in these studies to know the material characteristics of container loaded with an explosive. Since the force of a shock wave changes with the material of containers. To investigate the material characteristics of a container, the shock wave propagating in the material has analyzed. In this research, Polymethylmethacrylate (PMMA) which usually used as loading container of explosive used as container material. For analysis, the pressure measurement experiment by the manganin gauge (Kyowa Electric Industrial Co., ltd.,), numerical analysis by LS-DYNA3D (commercial program based on the explicit finite element code) and optical observation by high-speed are used. A lot of data about the shock wave propagating in PMMA was obtained.
