“…At the last phase of penetration when the core comes to rest in the rear layers of the light ceramic armor, most of the fractured ceramic from the point of impact gets ejected and removes energy from the impact site (Fig. 2f) [3]. It must be stated, that not all types of cracking absorb energy or the absorption ability is very limited.…”

“…First aluminum oxides ceramic armor panels were developed over 40 years ago. AD85 grade, with an alumina content of 85%, was the standard material in use for helicopter applications, as well as body armor plates [3]. Numerous investigations are made in order to achieve the most effective aluminium oxides armor composition.…”

This paper presents a review of the advanced materials used in the structure of a novel armor systems and the bodies or frames of the military equipment and vehicles. One of the most often materials engaged in armors are the ceramics among of which the aluminium oxides are the widest spread. Nevertheless, there are more advanced ceramics alike a silicon carbide or boron carbide used for example to shield the pilots of assault helicopters. The section of the paper concerning the materials for the bodies is focused on the high strength steels and the conditions of appropriate joints realization. The examples of the welding imperfections were showed and its influence on the structure integrity was discussed taking into account also others factors.

“…Also, the lower process time minimizes grain growth. The fine-grained microstructures and also the metastable phases may disappear in other types of sintering, however, the SPS method is capable of retaining these structures [15]. The SPS method is investigated widely both experimentally and numerically.…”

The present work aims to investigate the geometrical parameters of the graphite die on energy consumption needed for sintering of a ZrB2 sample. The Maxwell and electrical charge conservation equations are solved to obtain the electrical potential and current of the system. The governing equations are discretized by the Galerkin method and solved using the finite element method. The electric current distribution is obtained at each geometry and the temperature contours are obtained. The results showed that the height of die has a direct effect on power consumption. This can be attributed to the increased electric resistance and consequent increased Joule heating. On the other hand, increasing the die height resulted in more uniform temperature distribution through the sintered sample.
