Abstract

A unit cell structure of smooth surfaces was designed in this paper. By combining the orientations of the convex of the surfaces, four different models were presented. The mechanical properties of the models were studied by numerical analysis. The techniques of the representative volume element and the periodic boundary conditions were applied in the analysis. Little differences in the mechanical properties between the models with opposite convex orientations are found. The simulation results showed that the auxetic responses of the unit cell are universal at variant the geometric variables and parent material Poisson's ratios. The design concept is a highly effective method to fabricate cellular structures with similar frameworks.
