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.
