Penetration of a Shaped Charge
A shaped charge is an explosive device used to penetrate thick targets using a high velocity jet. A typical shaped charge contains explosive material behind a conical hollow. The hollow is lined with a compliant material, such as copper. Extremely high stresses caused by the detonation of the explosive have a focusing effect on the liner, turning it into a long, slender, stretching jet with a t...
متن کاملPenetration of Explosives by Shaped-charge Jets
Shaped-charge penetration of explosives is studied analytically and experimentally. Two models are developed, each applicable to a different regime of jet velocity. The first addresses high-velocity penetration. If a jet is sufficiently fast, its penetration velocity will exceed the explosive's detonation velocity, and the process may achieve a steady state with the crater following the detonat...
متن کاملApplication of Uintah-mpm to Shaped Charge Jet Penetration of Aluminum Application of Uintah-mpm to Shaped Charge Jet Penetration of Aluminum
The capability of the generalized interpolation material point (GIMP) method in simulation of penetration events is investigated. A series of experiments was performed wherein a shaped charge jet penetrates into a stack of aluminum plates. Electronic switches were used to measure the penetration time history. Flash x-ray techniques were used to measure the density, length, radius and velocity o...
متن کاملDetermination of Optimum Planar Imaging Parameters for Small Structures with Diameters Less Than the Resolution of the Gamma Camera
Introduction: The limited spatial resolution of the gamma camera hinders the absolute quantification of planar images of small structures. The imaged structures are affected by partial volume effects (PVEs), which can spread activity and lead to underestimation of the regional distribution. The use of optimum planar parameters reduces the impact of the limited spatial resolution of the gamma c...
متن کاملOptimum establishment of total station
At least two control points must be available in order to determine the position and orientation of a total station (TS). This paper analyses optimum horizontal location of TS with respect to the control points and gives an answer to question “What is the best location of total station with respect to the control points if the goal is to determine the coordinates of TS and detail points as prec...
