Numerical modeling of honeycomb structures in aerospace engineering is too tedious and time consuming. The homogenization of these structures permits to obtain an equivalent orthotropic homogeneous solid and its elastic effective properties and thus

This paper presents some general two- and three-dimensional finite element models to study the equivalent orthotropic mechanical properties of honeycombs. The models are developed on a representative volume element with appropriate periodic boundary

Architectured structures, particularly auxetic materials, have demonstrated encouraging applications in energy absorption as they facilitate the customization of their structural response. Specific geometries of unit cells can thus be tailored for pa
