"Auxetic material is a material which has negative Poisson’s ratio(NPR). Auxetic material shows some distinctive property like high energy absorbing property and high shear modulus. Among these, synclastic curvature is very interesting characteristic. When synclastic-curvature-material bends, it changes its shape like dome, contrary to non-auxetic material which changes its shape like saddle(anticlastic). This distinctive property could make it easy to manufacture curved structure like nose cone or wing panel in aerospace engineering. In this study, we studied a quantitative analysis about synclastic curvature of re-entrant panel with finite element model. We suggested a concept ‘Degree of Synclasticity(DOS)’, which means a ratio of curvature of load-direction and load-orthogonal direction. We studied the variation of DOS with two factor, unit cell inner angle() and load position angle(). DOS decreases as increases because the unit cell goes out of auxetic-shape. As varies, DOS changes in a large range. So proper optimization of would be needed for application."
