Pagination or Media Count:
Cylindrical charges with a longitudinal groove along one side were detonated in contact with a smooth steel block. A simple technique for measuring the depth of cut and deformation of the steel has been devised. It was possible to correlate the dimensions of the groove with the depth of cut obtained and the technique provides a simple means of comparing the efficiency of different shapes of groove.
