| Abstract |
The numerical study of dynamic behavior of concrete material under projectile impact has been widely done with the help of Holmquist-Johnson-Cook (HJC) constitutive material model due to its simplicity along with its worthwhile accuracy. In the present study, major governing HJC strength model parameters for ultra-high strength concrete (UHSC) i.e., fck=140 MPa are confirmed with the help of available triaxial compression test data whereas, other parameters of HJC material model are taken directly from open literature. The proposed parameters have been verified with the help of finite element analysis (FEA) using ABAQUS, by comparing the ballistic performance results in terms of ballistic limit velocity (BLV), impact and its corresponding residual velocities obtained from numerically with experimental study. Subsequent to the HJC model parameters verification, comparative study of ballistic performance of single and multi-layered UHSC targets against steel projectile with same overall thickness have been carried out numerically with the help of five different configurations. Followed by ballistic performance study on single layer with different thickness UHSC target against steel projectile. The present study finds to be beneficial for the optimization in the positioning of the anti-strike shield of protective structure as the behavior of the multi-layered concrete targets against the projectile impact are found to be very limited. |
