Special Issue Information

Dear Colleagues,

Additive manufacturing (AM) has revolutionized the field of materials and structural engineering, opening up new avenues for innovation and design in many industries. This Special Issue will highlight advanced materials and structures with high performances based on AM. It will also demonstrate the challenges and opportunities related to AM, such as improving material properties, enhancing structural performance, and optimizing process parameters. Topics of particular interest include, but are not limited to, the following:

  • Additive manufacturing processes, such as laser powder bed fusion, fused deposition modeling, digital light processing, etc.;
  • Advanced materials, such as composite materials, high-entropy alloy, fiber-reinforced polymer, etc.;
  • Multifunctional structures, such as porous structures, lattice structures, metamaterials, etc.;
  • Multifunctional properties, such as lightweight mechanical properties, sound absorption, energy absorption, thermal conductivity, etc.;
  • Advanced design approaches, such as artificial intelligence, multiscale optimization, material–structure–performance integrated design, etc.

The stress distribution within the struts of lattice metamaterials is non-uniform under compressive loads, with stress concentrations typically occurring at the node regions. Inspired by bamboo, this study proposes a type of body-centered cubic (BCC) lattice metamaterial with tapered prism struts (BCCT). The compressive behavior, deformation modes, mechanical properties, and failure mechanisms of BCCT lattice metamaterials are systematically analyzed using finite element methods and validated through compression tests. Parametric analysis is conducted to investigate the effects of key design parameters, including volume fraction, shape parameter, and material properties. The results reveal that BCCT lattice metamaterials effectively eliminate stress concentration at nodes by redistributing stress toward the center of the struts. This redistribution changes the failure mode from shear band failure to layer collapse, while the struts maintain a bending-dominated deformation mechanism under compression. The mechanical properties of BCCT lattice metamaterials are significantly influenced by the shape factor. Furthermore, the mechanical properties of BCCT lattice metamaterials with different volume fractions and materials are consistently superior to BCC ones, which verifies the effectiveness and adaptability of lattice metamaterials with taper prismatic struts for potential lightweight applications.
