“…Various recent studies with single-stage guns have operated with velocities well below this limit. 39,57,79,80 Two-stage guns, although capable of higher speeds than single ones, are limited with respect to projectile diameter (due to the necessarily smaller diameters in the launch tube) for an equivalent size and cost of machine. 67 These can be improved even further: for example, Zhao et al 81 report on the case where a two-stage LGG accelerated the projectile up to 7 km/s, and a secondary explosive apparatus attached to the muzzle accelerated it to 10 km/s.…”

This article presents a review of engineering and design aspects relevant to the mechanical and structural integrity of military vehicular armour, including materials-related technologies. Theoretical, experimental and numerical techniques for assessment are discussed and evaluated. A number of prominent material constitutive models are comparatively assessed.The Johnson-Cook model is shown to be particularly consistent in terms of agreement with experimental data, identification of material constants and ease of application. The article also discusses different numerical codes used and their relevance over time. Finally, it is argued that there is a need for a materials design tool for military vehicular armour.

“…In contrary to straight forward methodology of deriving empiric formulation, their limited applicability to various cases is a bottleneck for widespread usage. Analytical models are quite useful due to their direct applicability on various problems but derivation always requires simplified assumptions in governing equations which results in deviation from realistic outcomes [2,3]. It is inherent that, empirical and analytic approaches cannot capture the complex nature of impact phenomenon, thus numerical simulation has become a necessary tool for the study of ballistic penetration.…”

Determination of penetration depth at high velocity impact using finite element method and artificial neural network tools

Determination of ballistic performance of an armor solution is a complicated task and evolved significantly with the application of finite element methods (FEM) in this research field. The traditional armor design studies performed with FEM requires sophisticated procedures and intensive computational effort, therefore simpler and accurate numerical approaches are always worthwhile to decrease armor development time. This study aims to apply a hybrid method using FEM simulation and artificial neural network (ANN) analysis to approximate ballistic limit thickness for armor steels. To achieve this objective, a predictive model based on the artificial neural networks is developed to determine ballistic resistance of high hardness armor steels against 7.62 mm armor piercing ammunition. In this methodology, the FEM simulations are used to create training cases for Multilayer Perceptron (MLP) three layer networks. In order to validate FE simulation methodology, ballistic shot tests on 20 mm thickness target were performed according to standard Stanag 4569. Afterwards, the successfully trained ANN(s) is used to predict the ballistic limit thickness of 500 HB high hardness steel armor. Results show that even with limited number of data, FEM-ANN approach can be used to predict ballistic penetration depth with adequate accuracy.
