The localized low-velocity impact response of aluminium honeycombs and sandwich panels for occupant head protection: experimental characterization and analytical modelling
2007
Abstract This paper describes an investigation into the localized impact response of aluminium honeycombs and sandwich panels from the perspective of their use in occupant head protection applications. A programme of quasi-static and dynamic low-velocity impact testing using a hemispheric ‘head form’ impactor is described. From this, design data is presented in terms of acceleration histories and head injury criterion values. Furthermore, a simple analytical model is described for predicting acceleration histories for preliminary design purposes.
