“…Such models would be difficult to validate in the absence of a reliable method to measure jacket thickness variations nondestructively, both before and after impact. Present analytical models [3], [4], [5], [6], [7] and [8] consider only the gross geometry of bullets and make unjustified assumptions about the consistency and symmetry of the projectile and its casing. As such, a robust way to test correlation between ballistic performance and jacket thickness variation is desirable for the development of accurate numerical simulations.…”

AbstractFundamental to any ballistic armour standard is the reference projectile to be defeated. Typically, for certification purposes, a consistent and symmetrical bullet geometry is assumed, however variations in bullet jacket dimensions can have far reaching consequences. Traditionally, characteristics and internal dimensions have been analysed by physically sectioning bullets -an approach which is of restricted scope and which precludes subsequent ballistic assessment. The use of a non-destructive X-ray computed tomography (CT) method has been demonstrated and validated (Kumar et al., 2011 [15]); the authors now apply this technique to correlate bullet impact response with jacket thickness variations. A set of 20 bullets (9 mm DM11) were selected for comparison and an image-based analysis method was employed to map jacket thickness and determine the centre of gravity of each specimen. Both intra-and inter-bullet variations were investigated, with thickness variations of the order of 200 μm commonly found along the length of all bullets and angular variations of up to 50 μm in some. The bullets were subsequently impacted against a rigid flat plate under controlled conditions (observed on a high-speed video camera) and the resulting deformed projectiles were re-analysed. The results of the experiments demonstrate a marked difference in ballistic performance between bullets from different man...

“…Современные аналитические обзорные работы по проблеме удара и проникания [15][16][17] свидетельствуют о широком распространении модификаций модели локального взаи-модействия (МЛВ). В соответствии с одной из реализаций МЛВ давление в каждой точке боковой поверхности ударника отождествляется с давлением на внутренней поверхности сферической или цилиндрической полости, расширяющейся в безграничной среде от ну-левого радиуса до радиуса ударника («Cavity Expansion Model» в зарубежной литературе).…”

“…Dedicated surveys by Thompson and Mitchell [1]; Adeli et al [2]; Heuzé [3] are devoted to engineering models describing penetration into geological media. Papers and surveys by Backman and Goldsmith [4]; Brown [5]; Corbett et al [6]; Wen and Xu [7]; Ben Dor et al [8] and monographs by Bulson [9]; Carlucci and Jacobson [10]; Bangash [11]; Szuladziñski [12]; Seah et al [13] summarize some of the results obtained in the field. It must be emphasized that previously published overviews cover only a part of known analytical models and do not include the models suggested during the last decade and the models not published in English.…”

Abstract:The survey is dedicated to approximate empirical and analytical models which were suggested for describing high-speed penetration into geological shields. This review differs from the previously published reviews on this topic in the following respects: (i) includes a large number of models; (ii) describes models suggested during recent years; (iii) much attention is given to models which have been originally published in Russian and are not well known in the West. References list includes 81 items.
