Additively Manufactured Auxetic Structures: A Review

International Journal of Advanced Engineering and Technology Research
Auxetic structures exhibit mechanical behaviors that are significantly different from those of conventional materials. They expand laterally under tensile loading and contract laterally under compressive loading, which provides advantages in energy absorption, impact resistance, indentation resistance, and structural stability.

Wave motion in auxetic structures : A comparative numerical study of auxetic and non-auxetic structures

AbstractWave propagation in three periodic structure, specifically missing rib structure with chiral core (MRSC),rotating triangle structures with circular holes (RTCA) and square grid lattice (SGL), were investigatedthrough numerical simulation. The goal is to study how auxetic structures with altering area fractions differin structural properties ...

Experimental and numerical study on the out-of-plane behaviour of auxetic and hybrid auxetic structures

Abstract Auxetic Metamaterials having a negative Poisson’s ratio are gaining attention among researchers due to their excellent energy absorption characteristics.Most of the research on auxetic materials is focused on in-plane behaviour,while out-of-plane loads also influence auxetic materials in practical applications.
