Abstract To examine the influence of mesh density on blast loads anti-landmines (ALMs) and improvised explosive devices (IEDs) under an armored vehicle, models with different FE densities were numerically analysed. The multi-material arbitrary Lagrangian-Eulerian (MM-ALE) algorithm was used to simulate vehicle explosions. Explicit dynamic analysis performed in LS-DYNA. Blast loading simulation ...

Abstract In order to study the penetration ability of fragment simulation projectile(FSP) armored steel target, and detect protection target plates with different thicknesses. Combined numerical experiment, process FSP on thickness ratios is studied. The design implementation preparations were made for damage plate by fragments, relevant data obtained analyzed. analysis results show that finite...

this essay which is the ma theses of mr. hossein sarkheili draws our attention to the role of the armored unit in different operations from its early days. it can be considered a valuable essay because of different interviews the writer has done with the commanders who had responsibilities in irgc armored units. the writer has discussed this unit's function in different operations and in d...

Armored scale insects (Hemiptera: Diaspididae) are among the most invasive insects in the world. They have unusual genetic systems, including diverse types of paternal genome elimination (PGE) and parthenogenesis. Intimate relationships with their host plants and bacterial endosymbionts make them potentially important subjects for the study of co-evolution. Here, we expand upon recent phylogene...

formation of the armored unit in the early years of the imposed war can be considered as one of the most important achievements of irgc. considering the harsh and severe conditions of those days, this event took place with many difficulties. in addition to hardware scarcities, the chief commanders' opinion in irgc toward an armored unit was a greater problem to be overcome by the commander...

Abstract Armoring civilian vehicles requires specialized knowledge and experience that many armoring companies lack as they are not direct or indirect suppliers of vehicle manufacturers. This limits their access to automotive quality manufacturing certifications detailed designs, which can result in loss malfunctioning components during the process. Therefore, this study aimed investigate chall...

Seahorses and pipehorses evolved at least two independent strategies for tail grasping, despite being armored with a heavy body plating. To help explain mechanical trade-offs associated with the different designs, we created a "family" of 3D-printed models that mimic variations in the presence and size of their armored plates. We measured the performance of the biomimetic proxies across seven m...

Abstract. The location of objects based on the analysis acoustic signals is widely used in various civil and military systems. Applications that allow users to determine sound source are used, for example, conference rooms automatic speaker location, enabling unattended camera control, detecting tracking movement area surveillance systems, etc. paper presents a system determining azimuth moving...

In Quang Nam Province, then South Vietnam, on August 26, 1971, a convoy of United States Army armored patrol cars was returning to base at the end of the day. A rocket-propelled grenade struck one of the vehicles, and subsequently five of the soldiers were killed in action (KIA) while one was missing in action (MIA). After-action reports from eyewitnesses to the event described the MIA soldier ...
