SUMMARY:Landmines in the lab: experimental techniques for investigating hi
 gh velocity sand impacts - Dr G McShane\, CUED
DTSTART:20081128T140000Z

CONTACT:Ms Helen Gardner
DESCRIPTION:In developing novel\, lightweight materials for vehicle protec
 tion\, one challenging loading condition is that due to the detonation of 
 an explosive buried in soil.  The detonation of a landmine near to a vehic
 le subjects it to high velocity soil impact\, the precise nature of\nwhich
  depends on the properties of the soil\, the depth of burial of the explos
 ive and the height of the target above the soil surface.\nUnderstanding th
 e subsequent dynamic soil-structure interaction is essential in the develo
 pment of ffective protective materials.  Full scale experiments are costly
 \, hazardous and difficult to instrument and interpret.  The subject of th
 is talk is the development of experimental techniques to replicate the loa
 ding induced by the detonation of a buried explosive at a reduced scale ap
 propriate for laboratory investigations.  The development of the landmine 
 apparatus will be described\, its characteristics compared with results fo
 r real landmines\, and finally issues relating to scaling will be discusse
 d.
