Numerical Simulation of Projectile Penetration in Reinforced Concrete Panels

Numerical Simulation of the Reinforced Concrete Barrier Destruction at Impact

Submit Manuscript | http://medcraveonline.com interaction of airplane body with the shell has been replaced by impulse. Such approach is justified when initial stage of interaction is described, taking that concrete structure contacts quite thin aluminum body (from 3 to 8 mm thick). In this case one does not need to calculate contact boundaries thus simplifying significantly the objective and e...

Simulation of High-velocity Penetration for Rigid Projectile into Plain Concrete Target using Discrete Element Method

Analytical 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 ...

شبیه سازی عددی و تحلیلی پرتابه های فرسایشی سرعت بالا در اهداف بتنی مسلح به الیاف فولادی

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...

Numerical Simulation of Monitoring Corrosion in Reinforced Concrete Based on Ultrasonic Guided Waves

Numerical simulation based on finite element method is conducted to predict the location of pitting corrosion in reinforced concrete. Simulation results show that it is feasible to predict corrosion monitoring based on ultrasonic guided wave in reinforced concrete, and wavelet analysis can be used for the extremely weak signal of guided waves due to energy leaking into concrete. The characteris...
