Proceeding of: Fifteenth International Conference on Composite Structures (ICCS/15), 15th to 17th June 2009, Porto, Portugal0263-8223https://hdl.handle.net/10016/74737 pages, 9 figuresIn this study the perforation of composite sandwich structures subjected to high-velocity impact was analysed. Sandwich panels with carbon/epoxy skins and an aluminium honeycomb core were modelled by a three-dimensional finite element model implemented in ABAQUS/Explicit. The model was validated with experimental tests by comparing numerical and experimental residual velocity, ballistic limit, and contact time. By this model the influence of the components on the behaviour of the sandwich panel under impact load was evaluated; also, the contribution of the failure mechanisms to the energy-absorption of the projectile kinetic energy was determined.application/pdfeng© ElsevierSandwich structuresNumerical simulationHigh-velocity impactHoneycomb coreconference paperIngeniería MecánicaIngeniería Industrial10.1016/j.compstruct.2009.10.013open access209092096Composite Structures92
