Intensive investigation of the high velocity impact responses of newly designed sandwich panels with aluminium (AL) foam core and metal fibre laminate (FML) skins. Gas gun impact tests at a velocity of 210xA0;m/s. Study on the effect of the thickness of the foam core and FML skin on the impact resistance Development of a finite element model for effective numerical modelling of the impact behaviour of the sandwich panels Parametric study on the effect of the shape of projectile and impact angle on the impact behaviour of the sandwich panels using the FE model.
