dc.description.abstractAn orthotropic 3D re-entrant honeycomb structure that exhibits a negative Poisson’s ratio was designed and fabricated via the electron beam melting (EBM) process. The modeling work established the relationships between various structural parameters and the mechanical properties of the auxetic structures. Compressive tests were performed on the re-entrant honeycomb samples made with Ti6Al4V as well as pure copper. Results of the strength, modulus and energy absorption for the two materials were compared with the theoretical models in order to verify the theoretical predictions.en_US
