Proceeding of: 15th International Conference on Composite Structures (ICCS 15), Porto, Portugal, June 15-17, 20090263-8223https://hdl.handle.net/10016/74777 pages, 11 figuresThe dynamic flexural behaviour of sandwich beams, with composite face-sheets and a foam core, was analysed by developing a 3D finite-element model. To model the core behaviour, a crushable foam model was used. The Hou criteria were used to predict the failure of the face-sheets. Dynamic bending tests were performed to validate the numerical model. The comparison between numerical and experimental results in terms of contact-force histories, peak-force values, absorbed energy, and maximum displacement of both face-sheets was satisfactory. It was revealed that the collapse of the foam core under the impact region favoured the failure of the upper face-sheet.application/pdfeng© ElsevierComposite sandwich beamsNumerical modellingDynamic bending testsconference paperIngeniería MecánicaIngeniería Industrial10.1016/j.compstruct.2009.07.018open access228592291Composite Structures92
