Sandwich Structure

 

LOW VELOCITY IMPACT

 

The aim of the present work is to develop  and apply an energy-balance  model  similar  to  that outlined by Abrate  in  order  to predict the impact response  of a  foam-based  and honeycomb-based sandwich  structures.  The accuracy of the model will be investigated by varying the incident energy of the falling impactor as well as the properties of the foam core.

 

 

The impact response  of the sandwich  structures  was modelled using an energy-balance  model. Here, it  is assumed  that the target responds quasi-statically   during the impact  event and that the kinetic energy of the target is absorbed in bending,  shear and contact effect deformations.
