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 کاملتحلیل تجربی سرعت حد بالستیک اهداف بتنی هوادار سبک اتوکلاو شده تحت نفوذ پرتابه صلب
In this paper experimental analysis of ballistic limit velocity of autoclaved aerated concrete (AAC) targets under rigid projectile penetration is presented. Industrial blocks with dimension of 600*250*200(mm) were cut into 125*125*50(mm) samples, impacted by gas gun using three different nose shaped projectiles (flat, ogive and conic). In this study damage mechanism and penetration depth were ...
متن کاملAnalytical and numerical modeling of erosive projectiles into steel fiber reinforced concrete target
In this paper, modeling of high speed projectiles with different nose shapes, penetrating into steel fiber reinforced concrete is investigated. This is a novel study because it considers the length to diameter ratio of steel fiber as well as projectile length to diameter ratio and volume fraction of fiber used in concrete matrix on the impact resistance of steel fiber reinforced concrete fibers...
