  • Ballistic and physical properties of highly fractured alumina 
    Horsfall, Ian; Edwards, M. R.; Hallas, M. J. (Maney Publishing, 2010-11-01)
    It is known that ceramic materials in armour are often shattered by a penetrating projectile and the resistance to penetration is therefore dependent upon the properties of this failed material. A small explosive charge ...
  • Effect of heat treatment on small scale fragmentation of aluminium alloy 
    Edwards, M. R.; Deal, C (Maney Publishing, 2011-01-31)
    Small scale explosions, using a detonator, of 7075 aluminium alloy cylinders, 15-100 mm outside diameter, were carried out to investigate the effects of heat treatment on fragmentation. This was the finest for the strongest ...
  • The Mechanical and Ballistic Properties of Polycarbonate 
    Edwards, M. R.; Waterfall, H. (2008-05-27)
    Polycarbonate is commonly used as the material of riot shields. Firings of 8.3 g steel ball bearings at velocities of 23-98 ms-1 produced damage in the form of dents. Subsequent tensile testing showed a small drop in ...
  • Penetration of a glass-faced transparent elastomeric resin by a lead-antimony- cored bullet 
    Hazell, P. J.; Edwards, M. R.; Longstaff, H.; Erskine, J. (Elsevier Science B.V., Amsterdam., 2009-12-31)
    The penetration of the lead antimony-cored 7.62 mm × 51 mm bullet into a glass- faced polyurethane elastomeric polymer resin has been studied. The resulting craters in the resin contained elongated bullet core material ...
