Abstract

L'invention concerne des structures auxétiques, des feuilles auxétiques à refroidissement par effusion, des systèmes et des dispositifs dotés de structures auxétiques, et des procédés d'utilisation et des procédés de fabrication de structures auxétiques. Une structure auxétique comporte un corps élastiquement rigide avec des surfaces supérieure et inférieure opposées. Des première et seconde pluralités d'ouvertures allongées s'étendent à travers le corps élastiquement rigide à partir de la surface supérieure vers la surface inférieure. La première pluralité d'ouvertures allongées s'étend transversalement par rapport à la seconde pluralité d'ouvertures allongées. La première et/ou la seconde pluralité d'ouvertures allongées ont des formes déformées saillantes à travers le corps élastiquement rigide selon un angle oblique. Les ouvertures allongées sont configurées de manière coopérative pour conférer des performances à la contrainte souhaitées tout en présentant un comportement à rapport de Poisson négatif (NPR) dans des conditions de chargement plan macroscopique. À titre d'exemple, la structure auxétique peut présenter une réduction de la concentration de contraintes à proximité des ouvertures allongées et un rapport de Poisson d'environ -0,0001 à -0,9 %.
