This study proposes innovative bioinspired tubular metamaterial structures modeled after the zigzag patterns commonly found in natural systems. The straight, curved and their symmetrical counterparts serve as inspiration for design of a novel biomimetic tube. To enhance mechanical performance these tubes, circumferential stiffeners are incorporated, varying both quantity arrangement. Various samples fabricated using additive manufacturing, experimental testing combined with finite‐element analysis is employed to assess deformation behavior, energy absorption (EA), specific EA (SEA), effective Young's modulus ( E eff ). Results demonstrate that addition significantly enhances capacity behavior by overall Poisson's ratio enhancing stiffness. Straight tubes exhibit highest stiffness, while symmetric show up 33% improvement stiffener integration. Nonsymmetric configurations enhanced integration superior 52%. Stiffeners SEA 42% tubes. parametric further emphasizes critical role geometric parameters optimizing performance. These results provide valuable insights designing advanced high variety applications.
