mechanics of projectile penetration into non-cohesive soil targets
investigation of projectiles penetration phenomenon has been carried out in non-cohesive soil (sand) targets under dry, saturated and compacted conditions. analytical studies have been performed on the linear and non-linear soil models to obtain penetration depth formulae for ogival nose projectile and the results are verified by experimental studies. in present work, three ogival nose projecti...
متن کاملHard projectile penetration and trajectory stability
We present a general framework to describe the dynamics of a hard projectile penetrating into a solid target. Rigid-body dynamics, differential area force law and semi-empirical resistance function are used to formulate the motion of the hard projectile. The proposed model is capable of predicting the projectile trajectory under various oblique and yaw angles. Critical conditions for the occurr...
متن کاملAnalytical and Numerical Consideration of Projectile Density Effect on Its Penetration Ability in Alumina Armor
In this paper, penetration of high velocity impact of 4340 steel and tungsten carbide projectiles with specific shapes in to ceramic armor that includes 10 mm alumina (95%) is considered analytically and simulated with Ls-Dyna software. Bernoulli equation used to consider the penetration velocity in ceramics, shows that the penetration is better and easier by increasing projectile density. The ...

چکیده زبان سیستم کاملی ازقوانین است که برای ایجاد ارتباط و تبادل معانی مورد استفاده قرار می گیرد که در رابطه تنگاتنگ با روابط قدرتی افراد می باشد. این رابطه و قدرت افراد می تواند مستقیما در انتخاب ضمایر و سایر ساختارهای زبانی حتی در رفتار افراد تاثیرگذار باشد. در هرجامعه ای ، تقریبا نوعی روابط قدرتی درمیان افراد موجود می باشد و این رابطه درنحوه ی استفاده ی آنها در زبان منعکس می شود. بررسی ای...
15 صفحه اولMulti-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...
