    Abstract
  • For a given shaped charge, the effects of the grain size of a liner on the performance of shaped charge jets have been investigated with aid of fire tests and flash X-ray radiographs. It was shown from experimental results that the performance of copper liner shaped charge jets are strongly dependent on the grain size of an initial liner. The smaller the grain size, the greater the cumulative length and break-up time will be and the better is the performance of penetration. The mechanism was discussed simply.
