collapse. The mechanism of jet formation for metallic conical liners with a semi-angle (one-half of the conical apex angle) less than 60° is as described below. Wide angle conical liners and non- conical liners are discussed in Walters and Zukas (1989). Figure 5 shows a typical shaped charge configuration like that described above. Note that
DiPersio, Simon, and Merendino1 presented equations to determine the penetration depth and hole volume associated with a shaped charge jet impacting a given target. In particular, given jet and target material densities, pj and pt, jet break-up time, t1, initial jet tip velocity,
Basically scaling of a shaped charge depends on the use of the appropriate materials, geometry, and spacing which will result in optimum values for jet length and density to match the target requirements.
Shaped charge - Wikipedia
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or …
SCAP is user friendly and very inexpensive to run. It is designed for flexibility in shaped charge device configuration, choice of competing modeling techniques, and implementation of new models for various parts of conical shaped charge jet formation and penetration phenomena.
In this paper, two main research directions are used to investigate the shaped charge phenomenon and to evaluate its performance. These directions are: (i) analytical and (ii) numerical simulation.
data for the effect of spaced armour on shaped charges. It has been shown [1,2] that the shaped charge jet tip is disrupted when it exits from a finite thickness plate. This is due to longitudinal and radial shock wave effects in the jet causing mushrooming of the jet tip or enhanced particulation.
INVESTIGATION OF FACTORS AFFECTING THE SHAPED CHARGE …
Oct 15, 2021 · In this paper, the analytical model is only used to predict the influence of each shaped charge factor on jet penetration process through a metallic target. The main factors are: (i) liner...
Shaped charges are cylindrical explosive filled charges with hollow cavity at one end and a detonator on the opposite side of the cavity. They are known as hollow charges or sometimes as
In order to develop a tandem warhead that can effectively destroy concrete targets, this paper explores the penetration performance of shaped charges with different cone angles and liner materials into concrete targets by means of experiments.
