Highlights • This paper, inspired by the conguration of the hygroscopic keel tissue of the ice plant, deals with the analysis of a two-dimensional cellular material made of elongated hexagonal cells filled with an elastic material. • The assumption of the Born rule, in conjunction with an energy-based approach, provide the constitutive model in the continuum form. • It emerges a strong influence of the infill's stiffess and cell walls' inclination on the macroscopic elastic constants. In particular, parametric analysis reveals the system isotropy only in the particular case of regular hexagonal microstructure.

Workshop on Encounter of the third kind on Generalized continua and microstructures in Arpino, 3–7 April 2018: A review of presentations and discussions

“…Two examples were discussed that take into account the additional structural hierarchy. In order to offer concrete and relevant tools to engineers for developing future generations of materials with enhanced performance and unusual functionalities, a novel strategy to obtain a honeycomb with mutable cells was proposed, a technique based on the ancient Japanese art of kirigami [60, 61].…”

A Generalized Strain Energy-Based Homogenization Method for 2-D and 3-D Cellular Materials with and without Periodicity Constraints

“…Norris [18] proposed a homogenization method for periodic lattice structures and derived analytical formulas for effective properties of elastic networks, including pentamode metamaterials. Ongaro et al [19] employed a strain energy-based approach to homogenize 2-D cellular structures of honeycomb cells filled with an elastic material. Ai and Gao [20] provided an analytical model for predicting effective elastic properties of 2-D periodic star-shaped re-entrant lattice structures with the orthotropic symmetry and negative Poisson's ratios by using Castigliano's second theorem and the Timoshenko beam theory.…”
