SUMMARY:Energetic phenomena in an underwater environment - Robert H. Telli
 ng\, [dstl] Fort Halstead
DTSTART:20080529T150000Z
DTEND:20080529T160000Z
UID:TALK10731@talks.cam.ac.uk
CONTACT:Stephen Walley
DESCRIPTION:This talk will examine the events that occur when condensed ph
 ase explosives are detonated underwater\, in particular\, covering the phy
 sics of underwater shock\, bubble pulsation and boundary interactions. Als
 o\, the historical background and reasons for remaining interest in underw
 ater explosions (undex) to both Government and industry will be discussed.
   Although research is unsurprisingly dominated by military interest in th
 e subject there is also commercial/civilian interest in underwater explosi
 ons for use in metal forming\, for development of improved rock blasting c
 ompositions and seismic work - notably\, undex analysis was used in the fo
 rensic investigation to understand the Kursk submarine tragedy. A further 
 niche application of undex is as a research tool for calibrating equations
  of state for energetic materials. These applications will be discussed an
 d a potted account will be given of recent experiences with ‘undex trial
 s’\, covering the techniques employed for bubble and shockwave measureme
 nt and the difficulties encountered with this kind of experimental work.
