Numericai Simulation on Non-Normal Penetration into Reinforced Concrete
In this paper, a FEA model of non-normal(considering yaw angle and oblique angle) penetration into reinforced concrete is established by using software ANSYS/LS-DYNA. In order to validate the digital model which is sensitive to material parameters,mesh size,ect. Amounts of numerical simulations are performed. The numerical results of a process of peneration are compared with the experimental results, and a good agreement is obtained.In the study,the residual velocity and the ballistic attitude when a projectile penetrates into a reinforced concrete target are focused on, the relationship between positive yaw angle and negative yaw angle with the penetration capacity of the projectile is investigated. The results obtained by the numerical approach are useful for predicting the response of the penetration, and the proposed numerical simulation methods may be very beneficial to some experiment of perforation of reinforced concrete structures.
