“…The maximum stress is computed by the elasticity theory and the nominal stress by the uniform stress distribution. Stress concentration areas can be avoided by rapid alterations in the geometry by imparting suitable pits, grooves, fillets, chamfers, and notches [54], [63]- [65]. Roderick Lakes discovered that negative Poisson's ratios tend to lower the SCF in some cavity conditions while raising the same in others [52].…”

Auxetic materials with negative Poisson's ratios, display the unique behavior owing to their micro-structure or geometrical build. Auxetic materials resist deformities when subjected to uniaxial, biaxial, and shearing stresses. Cellular based materials are known for their excellent impact and shock energy absorption. When foams are incorporated with auxetic geometry, their impact energy absorption increases. Combination of auxetic materials with conventional materials yield semi-auxetic materials. Ideally, layered structures where facing materials are metallic sheets sandwiching polymeric foam cores are popular. The auxetic materials can be combined with conventional materials to obtain P-N-P and N-P-N semi-auxetic sandwiched structures with diverse potential in several applications like automotive, aerospace, sports equipment, and protective armors.

“…The mechanical metamaterials with negative Poisson's ratio exhibit lateral contraction under compression and lateral expansion under tension, whose behaviors are quite different from the traditional structural or bulk materials [1]. The unique deformation feature imparts the negative Poisson's ratio materials versatile properties, such as high shear strength [2], indentation resistance/impact resistance [3], surface isotropy [4], and fracture resistance [5]. Since the polyurethane foam with negative Poisson's ratio was first introduced by Lakes [6], many research groups have focused their efforts on developing new auxetic materials and seeking their potential applications, such as aviation and other defense industries [7], biomedical science [8,9], cushioning and protective Gear [10], sensors [11], and so on.…”

Structural metamaterial with negative Poisson's ratio often has low stiffness due to its porous structure. For engineering applications, the various strategies have been developed to enhance its stiffness but also weaken the negative Poisson effect. In this work, we propose a 3D reinforced re-entrant structure (RRS) by adding arrow structures to the classical re-entrant structure (RS), which is fabricated by photocuring 3D printing of photosensitive resin. The structure-properties correlative mechanism of RRS is systematically analyzed by combining experiment (quasi-static compression experiment) and finite element simulation (ABAQUS). It is found that the equivalent elastic modulus and negative Poisson's ratio of RRS can be tuned by various structural parameters (i.e. the thickness ratio η, the length ratio of the slant rod α, the length ratio of the vertical rod β, and the angle θ of the re-entrant cells). By optimizing the structure parameters, the equivalent elastic modulus of RRS with the negative Poisson’s ratio of -0.28 can be significantly increase to 13.67MPa, which is 12.32 times larger than that of RS with the same negative Poisson’s ratio. Due to the flexible design of stiffness and negative Poisson ratio, our proposed 3D reinforced re-entrant structural metamaterial provides a potential way for designing engineering materials with desirable performance.

“…Several reports are available on the impact behavior and energy absorption of 2D woven structures and 3D woven structures at the fabric and composite level with thermoset resins. 36,[38][39][40] However, rare literature is available on the impact performance of 3D woven auxetic reinforced thermoplastic composites. To the best of the author's knowledge, no published literature is available to study the effect of the interlacement pattern of binding yarn on the auxeticity of warp, weft, and bi-directional interlock structures and the impact performance of their corresponding composites using thermoplastic resins.…”

Inducing auxetic nature is one of the emerging techniques to enhance impact tolerance in 3D woven composites due to their unique bidimensional-energy dissipation capability. The conventional 3D orthogonal structure has inherent auxetic nature; however, such auxeticity is completely restricted due to brittle thermoset resins-based composites. To overcome this problem, three types of 3D woven auxetic structures were developed and used as reinforcement with thermoplastic resins, that is, polycarbonate (PC) and polyvinyl butyral (PVB). The results revealed that the warp interlock structure showed the highest auxeticity, while the bidirectional interlock structure showed the least auxeticity. Charpy and low-velocity impact tests were performed to evaluate the effect of auxeticity on the impact properties of corresponding composites. Warp interlock with PC showed 49% and 47% higher Charpy impact strength and force, respectively, than bidirectional interlock with PC resin. Similarly, the low-velocity impact test results of warp interlock showed 32% and 32.5% higher impact force and absorbed energy, respectively, in warp direction than bidirectional interlock with PC resin.
