Perforation mechanics of 2024 aluminium protective plates subjected to impact by different nose shapes of projectiles. Thin-Walled Structures, vol. 123, pp. 1-10.0263-8231https://hdl.handle.net/10016/32444This paper focuses on the mechanical behaviour of aluminium alloy 2024-T351 under impact loading. This study has been carried out combining experimental and numerical techniques. Firstly, experimental impact tests were conducted on plates of 4 mm of thickness covering impact velocities from 50 m/s to 200 m/s and varying the stress state through the projectile nose shape: conical, hemispherical and blunt. The mechanisms behind the perforation process were studied depending on the projectile configuration used by analyzing the associated failure modes and post-mortem deflection. Secondly, a numerical study of the mechanical behaviour of aluminium alloy 2024-T351 under impact loading was conducted. To this end, a three-dimensional model was developed in the finite element solver ABAQUS/Explicit. This model combines Lagrangian elements with Smoothed Particle Hydrodynamics (SPH) elements. A good correlation was obtained between numerical and experimental results in terms of residual and ballistic limit velocities.10eng© 2017 Elsevier Ltd.Atribución-NoComercial-SinDerivadas 3.0 EspañaAA 2024-T351PerforationBallistic limitEnergy absorptionFEM-SPHresearch articleIngeniería Mecánicahttps://doi.org/10.1016/j.tws.2017.11.004open access110Thin-Walled Structures123AR/0000021064
