A review of the integrity of metallic vehicle armour to projectile attack

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.
