DESCRIPTION:The presence of cavities in explosives is known to sensitize t
 he material and cause ignition where it wouldn't occur if the voids were n
 ot present. Numerical simulations of shock-induced air-bubble collapse in 
 water present the dominant physical mechanisms present in the collapse pro
 cess\, while multiple bubble cluster simulations provide a picture of the 
 interactions of the collapse of neighbouring cavities. This provides a str
 ong basis to approaching the level of understanding the physical mechanism
 s that contribute to the start of ignition in heterogeneous explosives.
