Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.

In the field of medical technology, specialized equipment utilizes tubular metastructures with a negative Poisson's ratio in vascular stents to reduce risk embolism. The deliberate incorporation auxetic structures into stent design offers several benefits over traditional stents. This study examines nonlinear instability and bending responses reentrant perfect imperfect 3D-printed metastructures. First, governing equations for tube geometric imperfections under transverse axial mechanical loads are derived using von-Kármán assumption Timoshenko theory. Then, principle virtual displacement. physical characteristics structure Malek-Gibson relations, while tensile tests digital image correlation (DIC) used determine properties polylactic acid (PLA). Scanning electron microscopy (SEM) images help investigate variations modulus elasticity ultimate strength dogbone specimens, Ritz method Chebyshev polynomials is employed discretize equations. Second, two numerical algorithms analyze static behavior metatube within framework. validation conducted representative volume element (RVE) unit cell based on literature finite software Abaqus. Following mathematical model, an extensive investigation assess how differing parameters impact analysis tube.
