Abstract

Multiscale experiments are performed to understand the deformation mechanisms in polymer bonded explosives at a range of impact velocities. The experiments are conducted in a direct impact configuration, where a polycarbonate projectile is directly shot onto polymer bonded sugar samples at different impact velocities. During the deformation process, the images are captured at five million frames/second using an ultrahigh speed camera. For the macro scale experiment, the images are captured at a resolution of 75 μm/pixel and for the mesoscale experiments, the magnification factor is 10 μm/pixel. The deformation field is obtained using digital image correlation technique. From the macroscale displacement field, the spatial stress distribution is calculated using a nonparametric method. The meso-scale experiments are used to explain the deformation mechanisms observed at the macroscale.
