Abstract

Crustaceans in nature exhibit a Bouligand-type helicoidal fiber structure, giving them exceptional damage and impact resistance. Honeycomb plates, known for their lightweight and high strength, are extensively used in aerospace, transportation, and architecture. This study presents a novel biomimetic helicoidal honeycomb plate (HHP) that combines the benefits of both these structures. By varying cell geometries (15, 12.5, 10, and 7.5 mm) and helicoidal angles (0°, 60°, 120°, and 180°), the mechanical response of the HHP to blast loadings is examined. Results indicate that the helicoidal angle significantly improves blast resistance. Specifically, the 180° helicoidal angle with 15 and 12.5 mm cell geometries provides the highest blast resistance, while the 120° angle performs best for 10 mm cells and the 0° angle for 7.5 mm cells. To achieve optimal blast resistance, balancing rigidity and toughness is essential. Increasing the helicoidal angle improves blast resistance, especially in structures with lower rigidity. These insights are crucial for the design of advanced protective structures, offering valuable guidance for blast and impact protection in the fields of protective and safety engineering.

期刊介绍： The International Journal of Mechanical Sciences (IJMS) serves as a global platform for the publication and dissemination of original research that contributes to a deeper scientific understanding of the fundamental disciplines within mechanical, civil, and material engineering. The primary focus of IJMS is to showcase innovative and ground-breaking work that utilizes analytical and computational modeling techniques, such as Finite Element Method (FEM), Boundary Element Method (BEM), and mesh-free methods, among others. These modeling methods are applied to diverse fields including rigid-body mechanics (e.g., dynamics, vibration, stability), structural mechanics, metal forming, advanced materials (e.g., metals, composites, cellular, smart) behavior and applications, impact mechanics, strain localization, and other nonlinear effects (e.g., large deflections, plasticity, fracture). Additionally, IJMS covers the realms of fluid mechanics (both external and internal flows), tribology, thermodynamics, and materials processing. These subjects collectively form the core of the journal's content. In summary, IJMS provides a prestigious platform for researchers to present their original contributions, shedding light on analytical and computational modeling methods in various areas of mechanical engineering, as well as exploring the behavior and application of advanced materials, fluid mechanics, thermodynamics, and materials processing.
