Comparison of Numerical Simulation Techniques of Ballistic Ceramics under Projectile Impact Conditions.

This article presents an analysis of the effectiveness of available numerical techniques in mapping the characteristic behavior of ballistic ceramics under projectile impact conditions. As part of the work, the ballistic tests were performed on the layered ceramic/steel composite armor and tested with the 7.62 × 39 mm, armor-piercing incendiary (API) BZ projectile.

Experimental and Numerical Study on the PG-7VM Warhead Performance against High-Hardness Armor Steel.

Analyses presented in the article were carried out in order to characterize the main parameters of the shaped charge jet formed due to detonation of the PG-7VM warhead. As opposed to the previously published studies in which rolled homogeneous armored steel was mainly used as a target, in the current work the warhead penetration capability was determined against more contemporary high-hardness (500 HB) ARMSTAL 30PM steel armor with precisely determined mechanical properties. The research included experimental depth of penetration tests and their numerical reproduction in the LS-Dyna software.

Assessment of the Impact Resistance of a Composite Material with EN AW-7075 Matrix Reinforced with α-AlO Particles Using a 7.62 × 39 mm Projectile.

The paper presents the results of studies on the effects of shooting composite materials produced by pressure infiltration with the EN AW-7075 alloy as a matrix and reinforcement in the form of preforms made of α-AlO particles. Composite materials were made with two reinforcement contents (i.e.
