Local deformation and failure mechanisms of polymer bonded energetic materials subjected to high strain rate loading
The dynamic multi-scale deformation mechanism of polymer bonded energetic material is
investigated. Samples made of polymer bonded sugar (a known simulate for polymer
bonded explosives) with 85% sugar crystals and 15% polymer binder are used. The
samples are dynamically compressed using a split Hopkinson pressure bar. Using a high
magnification, meso-scale 2D digital image correlation experimental setup, the local
deformation is measured in situ at sub-grain scale. The macroscale deformation mechanism …
