SUMMARY:The properties of silicate glass relevant to their use in ballisti
 cs applications - Stephen Walley\, SMF Group\, The Cavendish Laboratory
DTSTART:20140515T150000Z

CONTACT:Stephen Walley
DESCRIPTION:The aim of this talk is to give an introduction to the literat
 ure on the use of silicate glasses in ballistics applications. The applica
 tions that will be discussed include optically transparent windows (where 
 their amorphous nature\, appropriate band gap\, hardness and cheapness mak
 e them ideal window materials) as well as layers in opaque armours designe
 d to be resistant to shaped charges. In the latter application\, their inc
 rease in volume (bulking) on fracture disrupts the shaped charge jet. Othe
 r topics that will be covered include low-velocity damage by windborne deb
 ris\, liquid and solid impact\, dynamic methods of testing (Hopkinson pres
 sure bar\, Taylor impact\, and plate impact shock loading)\, and constitut
 ive models. The use of glass as a shaped charge material will also be pres
 ented.\n
