Tunable compressive properties of a novel auxetic tubular material with low stress level

The auxetic tubular materials have attracted wide attention owing to their unusual mechanical properties and potential applications in designing foldable devices. However, most of auxetic tubular structures designed by incorporating re-entrant, chiral or penetrated microstructures remain great challenging in stress concentration because of the presence of shape corners in these structures. In this study, a novel auxetic tubular structure is...
