Simulation and experimental study of fragment penetration into armored steel plate

Abstract

In order to study the penetration ability of fragment simulation projectile(FSP) to armored steel target, and to detect the protection ability of target plates with different thicknesses. Combined with numerical simulation and experiment, the penetration process of FSP on armored steel target plates with different thickness ratios is studied. The design and implementation preparations were made for the damage of the steel target plate by the fragments, and the relevant data were obtained and analyzed. The analysis results show that the finite element analysis and the experimental study are in good agreement, and the ballistic limit of armored steel targets with different thicknesses and the calculation formula of the residual velocity of the FSP are obtained. The research results provide the basis and support for the evaluation, design and improvement of armored vehicle protection capability.

The effect of polyurea position and thickness on the resistance elastic energy of polyurea composite plate

“…Both the core and the steel plate are used plate using Johnson-Cook model, the core parameters [7] and steel plate parameters [8] are shown in Table 6. The six-parameter Mooney-Rivlin model was chosen for the polyurea material, and the parameters [9] are shown in Table 7.…”

Using an Internal State Variable Model Framework to Investigate the Influence of Microstructure and Mechanical Properties on Ballistic Performance of Steel Alloys

“…A wealth of experimental and numerical model data pertaining to material ballistic impact performance exist in the literature. The behavior of a variety of metal plates subjected to normal and oblique impacts by projectiles of varying shapes, sizes, and materials has been discussed [20,[43][44][45][46][47][48][49]. Additionally, ref.…”
