Quasi-static mechanical behaviors of arc curved crease origami metamaterials
This paper introduces a novel arc curved crease origami (ACCO) metamaterial based on Miura origami, that shows improved specific energy absorption, indicating a major advancement over traditional Miura origami. The quasi-static mechanical properties and energy absorption characteristics of the ACCO metamaterials were studied through experiments and finite element analysis. Results reveal that the ACCO metamaterials’ tailored inter-shell angles ensure consistent enhanced performance and energy absorption across all compression directions, offering lightweight and durable structures with versatile anisotropic properties. The bi-directional graded design of ACCO metamaterials, featuring adjustable shell angles, central angles, and cell thicknesses, has resulted in a new class of lightweight, high-energy-absorptive metamaterials. Our research confirms that advanced ACCO metamaterials optimize energy absorption efficiency and possess an enhanced energy dissipation system, outperforming traditional origami metamaterials. These findings suggest that ACCO metamaterials are promising for energy absorption applications and provide valuable design principles for origami-based energy absorption devices.
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.
