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 کاملa novel study of penetration into concrete targets by ogive nose projectiles
in design of defense structures, concrete are often used to provide protection against incidental dynamic loadings such as the impact of a steel projectile. in the present study, a new analytical model is proposed to predict penetration depth into concrete targets by ogive nose projectile. hence, to develop the model and simulate penetration of high velocity ogive-shape nose steel projectiles...
متن کاملModifications to Walker-Anderson Model for Analysis of High-velocity Penetration of an Eroding Long-rod Projectile into Semi-infinite Concrete Targets
This paper presents a modified form of the Walker-Anderson (W-A) model for analyzing high velocity penetration of an eroding projectile into a concrete target in which the W-A model is improved by incorporating calculations for the plastic flow field of concrete in terms of its compressibility and strain rate sensitivity under severe pressure. With the changes to and calculations of plastic fie...
متن کاملPerformance of High-strength Concrete
This research was undertaken to investigate performance of high-strength concrete incorporating mineral admixtures, fly ash and silica fume. For modern construction, the use of new construction materials is increasing to achieve economy and improved final results. An extensive literature search was carried out to review various engineering properties of high-strength concrete. In this study, th...
