Sandwich structures based on Fibre Reinforced Polymer (FRP) facesheet skins bonded with low density aluminium foam core are increasing in use in aerospace and marine industries. These structures are very sensitive to high velocity impact during the service. Therefore, it is necessary to study the energy absorption of the structures to ensure the reliability and safety in use. Experimental investigation of these transient events is expensive and time-consuming, and nowadays the use of numerical approaches is on the increase. Hence, the purpose of this paper is to develop a numerical model of sandwich panels with aluminium foam as a core and Glass, Carbon and Kevlar Fibre Reinforced polymer composite as faceplate, subjected to high velocity impact using ABAQUS/Explicit. The influence of individual elements of the sandwich panel on the energy absorption of the structures subjected to high velocity impact loading was analysed. Selection of suitable constitutive models and erosion criterion for the damage were discussed. The numerical models were validated with experimental data obtained from the scientific literature. Good agreement was obtained between the simulations and the experimental results. The contribution of the face sheet, foam core on the impact behaviour was evaluated by the analysis of the residual velocity, ballistic limit, and damaged area.

A finite element model is developed in this paper to simulate the perforation of aluminium foam sandwich panels subjected to high velocity impact using the commercial finite element analysis software LS-DYNA. The aluminum foam core is governed by the material model of crushable foam materials, while both aluminium alloy face sheets are modeled with the simplified Johnson-Cook material model. A non-linear cohesive contact model is employed to simulate failure between adjacent layers, and an erosion contact model is used to define contact between bullets and panels. All components in the model are meshed with 3D solid element SOLID 164. The developed finite element model is used to simulate the dynamic response of an aluminium foam sandwich panel subjected to projectile impact at velocity ranging from 76 m/s to 187m/s. The relationship between initial velocity and exit velocity of the projectile obtained from numerical modelling agrees well with that obtained from experimental study, demonstrating the effectiveness of the developed finite element model in simulating perforation of sandwich panels subjected to high velocity impact.

This paper first presents an experimental investigation into the response of square sandwich panels with an aluminium foam core under blast loading, followed by a corresponding FE simulation using LS-DYNA. In the simulation, the loading process of explosive and response of the sandwich panels have been investigated. The blast loading process includes both the explosion procedure of the charge and interaction with the panel. The simulation result shows that the deformation/failure patterns observed in the tests are well captured by the numerical model, and quantitatively a reasonable agreement has been obtained between the simulation and experiment. Finally, a parametric study has been carried out to investigate the energy absorption performance of sandwich panels.
