    High-speed photography has been used to investigate the dynamic behaviour of similar grades of WC-Co hardmetals during ballistic impacts with velocities in the range of 28-484 m/s. Key features of the failure of similar ...
  • Stennett, C.; Cooper, G. A.; Hazell, P. J.; Appleby-Thomas, G. J. (AIP American Institute of Physics, 2009-12-31)
    There is considerable evidence that secondary explosive materials having a relatively large (10-12%) proportion of HTPB binder do not exhibit DDT under cook-off. However, the understanding of the mechanisms controlling ...
  • Appleby-Thomas, G. J.; Wood, D. C.; Hameed, A.; Painter, J.; Le-Seelleur, V.; Fitzmaurice, B. C. (Elsevier, 2016-04-01)
    For both ethical and practical reasons accurate tissue simulant materials are essential for ballistic testing applications. A wide variety of different materials have been previously adopted for such roles, ranging from ...

    The shock response of chromium sulfide-chromium, a cermet of potential interest as a matrix material for ballistic applications, has been investigated at two molar ratios. Using a combustion synthesis technique allowed for ...
  • Appleby-Thomas, G. J.; Hazell, P. J.; Wilgeroth, J. M.; Shepherd, C. J.; Wood, D. C.; Roberts, A. (American Institute of Physics, 2011-12-31)
    Plate-impact experiments have been employed to investigate the dynamic response of three readily available tissue simulants for ballistic purposes: gelatin, ballistic soap (both subdermal tissue simulants), and lard ...
  • Appleby-Thomas, G. J.; Wood, D. C.; Hameed, A.; Painter, J.; Fitzmaurice, B. (Elsevier, 2016-10-29)
    In this paper in order to try and elucidate the effects of particle morphology on ballistic response of comminuted systems, a series of experiments were carried out via the use of powder compacts with differing initial ...
