Numerical Simulation of Penetration into Concrete Target Using SPH-Lagrange coupling Method
In analaysis of dynamic fracture of concrete and penetration performance of projectiles, the SPH-Lagtrange coupling method is a useful and powerful approach. This work demonstrates the application of both numerical simulation by SPH and empirical equation of ConWep in predicting the penetration of a concrete target by an ogive-nosed projectile. The results from the experiment performed by Buzaud et ac are used as a benchmark for comparison. In the numerical simulations the 3.0-caliber radius-head steel ogival-nose projectiles with different mass and different diameter are fired against cylindrical concrete target with a striking velocities of 292, 276 and 510 m/s. In the simulation the smooth particles hydrodynamics SPH-Lagrange coupling method is applied to predict the maximum depth of penetration(DoP). For calculation of DoP and response of projectile the SPH-Lagrange method can give satisfactory results.
