- Review of Mechanics and Applications of Auxetic Structures (2014, methodology): “The auxetic materials have a natural tendency to form dome-shaped doubly curved (synclastic) surfaces (in Figure 6), unlike conventional materials which tend to form saddle-shaped surfaces [2, 3].”
- Elastic properties of chiral, anti-chiral, and hierarchical honeycombs: A simple energy-based approach (2016, background): “novel prostheses [26], fasteners [27], piezo-composites with optimal performance [28], dome-shaped panels [29,30], and high structural integrity foams [31].”
- Elasticity of anti-tetrachiral anisotropic lattices (2013, background): “2(a)): ex ¼ 2ðr t=2Þ/ Lx ð1Þ ey ¼ 2ðr t=2Þ/ Ly ð2Þ The in-plane Poisson’s ratio mxy can be calculated from its definition (Evans and Alderson, 2000b): mxy ¼ ey ex ¼ Lx Ly ð3Þ The energy approach is used here to obtain the in-plane linear elastic modulus.”
- Morphing aircraft based on smart materials and structures: A state-of-the-art review (2016, background): “Unlike traditional honeycomb structures, an auxetic structure is one that becomes wider when it is stretched (Evans and Alderson, 2000), and therefore, it has a negative Poisson’s ratio (Prawoto, 2012).”
- In-plane crashworthiness of re-entrant hierarchical honeycombs with negative Poisson’s ratio (2019, background): “Because of the negative Poisson’s ratio, the auxetic structures have distinctive mechanical properties and good energy absorption ability [12].”
- In-plane elasticity of a novel auxetic honeycomb design (2017, background): “NPR honeycomb structures feature synclastic curvature behavior, therefore making possible to provide dome-shaped surfaces when loaded with out-of-plane bending deformation [30,32].”
