Abstract:
To analyze the law of high strength steel projectile penetrating low strength steel target,the numerical simulation and experiment on long-rod 35CrMnSiA projectiles with the velocity of 1.0~1.8 km/s penetrating into infinite thickness A3 steel targets with hydro-code AUTODYN are presented here.The finite element-smoothed particle hydrodynamics(FE-SPH) coupling method and the depth of penetration(DOP) method are applied in the simulation and experiment.The numerical predictions of depth of penetration and the residual length of projectile show good agreement with experimental observations,which shows good applicability to the high velocity penetration simulation.The results show the penetration processes can be divided into the fragments penetration and rigid projectiles penetration,and there is a rule of depth monotone non-increasing variation and residual length of projectile monotone decreasing variation with striking velocity.
