Devoted to the subject of shape charge design using numerical methods, this book offers the defense and commercial industries unique material not contained in any other single volume. The coverage of the Lagrangian and Eulerian methods as well as the equation of state provides first hand help to engineers working on shape charge problems.
For concrete targets by the compressive and tensile damage model, in order to obtain the CRA, Liu et al. have conducted numerical simulations of oblique angle penetration by using the 3D finite element code LS-DYNA. They presented that the ballistic trajectory at different oblique angles and the ricochet are numerically simulate by using a semi Failure analysis of semi-infinite concrete targets Improving the penetration efficiency of missiles into concrete is a practical research topic. In this paper, a tubular projectile was designed to enhance penetration diameter on concrete targets. To validate numerical simulation methods, an experiment of an ogive-nosed projectile penetrating a semi-infinite concrete target was reproduced by numerical simulation.
Numerical simulations of oblique-angle penetration by deformable projectiles into concrete targets are performed in this paper by using the three-dimensional finite element code LS-DYNA, into Numerical Simulation of Projectile Oblique Impact on In the present study, the microspacecraft bulkhead was reduced to the double honeycomb panel, and the projectile oblique hypervelocity impact on the double honeycomb panel was simulated. The distribution of the debris cloud and the damage of a honeycomb sandwich panel were investigated when the incident angles were set to be 60°, 45°, and 30°. The

In order to demonstrate the convergence of the numerical method, the whole area is divided into 0.5 million, 1 million, 1.5 million, and 2 million units, respectively. The sizes of corresponding grid are gradually refined. The cylinder enters the water vertically at a speed of 14.37 m/s.
PELE (Penetrator with Enhanced Later Effect) is a new type of ammunition, which does not need to be filled with explosives and fuses, but has the function of armor piercing projectile and grenade at the same time. The numerical simulation of a 60 mm diameter PELE penetrating target was investigated. The results show that in the process of the target plate becoming thicker, the Numerical simulation of long rods impacting silicon Dec 01, 2006 · The numerical simulations of oblique impacts on the 15 mm thick SiC and steel base plates are conducted for different angles of obliquity. The comparison between the predicted total penetration depth on the combined ceramic and steel base plate and the experimental measured data from is shown in Table 5. For the normal impact, the predicted
Feb 01, 2004 · The various numerical simulations presented the details of penetration processes, distributions of energy, stresses etc. of normal and oblique impact at a velocity of 315 m/s. In particular, it was found that the distributions of global kinetic, internal and total energy versus time are similar for normal and oblique impact.
