Abstract:
In this article, four new semi-auxetic structures are designed by changing the way of interface connection and adding external frames. These structures were fabricated by fused deposition modeling, which is an additive manufacturing technology. The effects of interface design and external frame on deformation mode and energy absorption performance of semi-auxetic structure under quasi-static compression are studied. It was found that the deformation modes of framed and frameless structures are different. The specific energy absorption of the semi-auxetic structure is increased by ∼52% compared with the frameless hexagonal honeycomb structure. In addition, Abaqus was used to establish finite element models of the four new semi-auxetic structures and the frameless hexagonal honeycomb structure. It can be found that the simulation results were consistent with the experimental results.
