Abstract

This study innovatively proposes a locally activated magnetically responsive 4D printing strategy to solve the problem of local deformation of magnetic shape memory composites. The local activation scheme is designed to precisely regulate the thermal activation area and magnetic field parameters, and the deformation behavior of the composites can be finely controlled. In addition, the strategy is applied to the shape tuning of the dome and chiral structures, which realizes the intelligent programming of structural energy absorption properties. This study opens up new avenues for the design and fabrication of adaptive and reconfigurable active mechanical metamaterials, minimally invasive medical implantable devices, and flexible electronic 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.
