Damage Mechanics Modelling of the shear nonlinear behavior of Nomex honeycomb core. Application to sandwich beams

Abstract: In this work, a modelling strategy based on damage mechanics is presented for Nomex honeycomb core. The proposed approach is based on the experimental analysis presented by the authors in [1] and consists of the decoupled modelling of the buckling and collapse of cells for the HRH-78 Nomex honeycomb core with two damage parameters. The proposed approach shows good agreement with the experimental tests. The computational cost is low, proving the efficacy of this technique. This strategy may avoid using full 3D … Show more

“…This model is not as detailed as the models developed by Roy et al in [20], Seeman et al in [14,31] or Slimane et al in [32]. Instead, several simplifications proposed by ESA in [10] and the ideas and results presented previously in [27,33] are considered. These simplifications reduce the development and Fig.…”

“…As for the types of elements, only brick elements are used to represent the materials, including the skins, the honeycomb core, the potting and the fastener. For the core, this allowed the CDM approach presented in [33] to be implemented, providing a good alternative to include the shear nonlinear behavior of the core at low computational cost.…”
