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 کاملThe Pattern of Caspian Sea Water Penetration Into Anzali Wetland: Introduction of a Salt Wedge
Measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of Caspian Sea penetration into Anzali Wetland was determined. The results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. A pattern of saltwater and freshwater interface is presen...
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 Method for Predicting Pile Capacity Using Cone Penetration Test Data
The massive construction in poor lands has encouraged engineers to use deep foundations in order to transfer superstructure loads to the subsoil. Since soil excavation, sampling, and laboratory testing as a part of site investigation are relatively difficult, in-situ tests such as cone penetration test (CPT) as a very informative test may be recommended. The CPT has been widely used in engineer...
متن کاملMulti-objective Optimization of a Projectile Tip for Normal Penetration
The main purpose of the present work is multi-objective shape optimization of a projectile tip for impacting and normal penetrating. Velocity drop, weight and inner volume of projectile have been considered as three conflicting objective functions. For this purpose, at the first step, finite element modeling was done using ABAQUS/Explicit and projectile penetration was examined in different ge...
