| المستخلص: | Numerical investigation has been undertaken to study the process of target penetration by fragment of high explosive warhead. Finite element modeling of target plates and penetrators using ANSYS LS-DYNA. Fragment simulating projectile (F.S.P) of 1.411 grams and 1.912 grams are used, normally impacting a thin mild steel target plates of 1.25 mm and 2.2 mm thick. Simulating velocities ranged from 450 m/s to 950 m/s. Comparison of finite element simulation parameters to experimentally available data in literature do show an overall very good agreement for residual velocities and a satisfactory agreements for plug thickness. Model over estimates plug thickness this might be due to the method of estimating perforation geometry, there are also some discrepancy of residual velocities, these might be contributed to utilization of static material properties rather than dynamical values or that these velocities are close to ballistic limit velocity. |
