The First Years Los Alamos, New Mexico: Non-homogeneous distribution of the inclusions can also be achieved. Embed Penetration kinetics of a cumulative jet into brittle materials. Los Alamos National Laboratory, , pp. However, the effect of the radial action has not been quantitatively estimated. In this work, we study the penetration kinetics of a CJ into a BM to describe it in terms of a hydrodynamic cumulation theory. Over time, the particles tend to fall out of alignment, which reduces the depth of penetration at long standoffs.
Cumulative charge penetration brittle material
In addition to drawings and performance specifications, material specifications should be reviewed for significant characteristics relating to properties, performance, handling, and storage requirements. For the deepest penetrations, pure metals yield the best results, because they display the greatest ductility, which delays the breakup of the jet into particles as it stretches. Naval Torpedo Station at Newport, Rhode Island , he noticed that when a block of explosive guncotton with the manufacturer's name stamped into it was detonated next to a metal plate, the lettering was cut into the plate. A description of Munroe's first shaped-charge experiment appears on p. Los Alamos National Laboratory, , pp. The key to the effectiveness of the hollow charge is its diameter.

Because of the variation along the liner in its collapse velocity, the jet's velocity also varies along its length, decreasing from the front. A Comp-B loaded shaped charge with a rounded or pointed cone apex with a copper liner had an average temperature of degrees Celsius with a standard deviation of 67 degrees Celsius.
Kinetics of cumulative jet penetration into glass
Description: Rumyantsev 1 Email author 1. He can be reached via email at nathaniel. Also, at the apex of the cone, which forms the very front of the jet, the liner does not have time to be fully accelerated before it forms its part of the jet.
