Discrete Modeling of the Crushing of Nomex Honeycomb Core and Application to Impact and Post impact Behavior of Sandwich Structures By Bruno Castanié, Yulfian Aminanda, Jean Jacques Barrau and Pascal Thevenet

The crushing of Nomex honeycomb structures is very complex, with wrinkling, tearing and damage to the phenolic resin layer []This complex behaviour can be modelled according to various

They observed in impact tests that soft bodies impacting on Nomex honeycomb cored sandwich caused a shallow crushing of the coreContrarily, hard bodies caused deeper and severe damageThey additionally modelled the impact cases and obtained a good agreement between experimental and numerical results.

In this chapter, an original method for modeling the behavior of sandwich structures during and after impact is proposed and validatedIt is based on the demonstration that Nomex honeycomb behaves in a post buckling mode very early and that compression forces are taken up by the corners or vertical edges of the honeycomb cells in the same way as they are in the stiffeners in aircraft structures.
