Under shock loading, metals have been found to melt and with reflection of the shock wave
from the material free surface, cavities nucleate and grow. This process is referred to as
micro spall and has been studied experimentally with analytical models describing debris
sizes. Measurements during the cavity growth phase are not possible at present and we
