a 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 کاملAnalysis of Normal Penetration of Ogive -Nose Projectiles into Thin Metallic Plates
In this note, a theoretical model for analyzing of normal penetration of the ogive – nose projectile into metallic targets is presented .The failure is assumed to be asymmetry petalling and the analysis is performed by using the energy balance and work done .The work done consist of the work required for plastic deformation Wp, the work for transferring the matter to new position Wd and the wor...
متن کاملPlastic Wave Propagation Model for Perforation of Metallic Plates by Blunt Projectiles
In this paper, a six-stage interactive model is presented for the perforation of metallic plates using blunt deformable projectiles when plastic wave propagation in both target and projectile is considered. In this analytical model, it is assumed that the projectile and target materials are rigid – plastic linear work hardened. The penetration of the projectile into the target is divided into s...
متن کامل3D Finite Element Modeling of High Speed Machining
This paper presents simulation of High Speed Machining of steel with coated carbide tools. More specifically, Third Wave Systems AdvantEdge commercial Finite Element Method code is employed in order to present turning models, under various machining conditions. As a novelty, the proposed models for High Speed Machining of steel are three-dimensional and are able to provide predictions on cuttin...
متن کاملThe Penetration of Rock by High-speed Water Jets
The effect of pressure, stand-off distance and time on the penetration of sandstones by a 0.84 mm. jet of water was investigated. Pressures ranged up to 9000 lb/in 2 (62 MN/M), stand-off distances to 2 in. (5.08 cm) and time from 0.5 to 30 sec. The effect of using a friction reducing agent was determined. The advantages of allowing the spent jet to escape and not interfere with penetration are ...
