摘要：

The current technological development has put forward higher requirements for the multifunctionality of materials and structures. This study delves into the bandgap attributes of a zigzag connection (ZC) lattice metamaterial, capable of being constructed through the mirroring or rotation of basic units. This metamaterial exhibits nearly zero thermal stress when subjected to thermal expansion deformation. Through a comprehensive analysis and comparison of three distinct arrangements, the rotational symmetrical quadruple cell emerges as the optimal choice. Subsequently, the investigation explores the influence of various geometric dimensions, constituent materials, and additional parameters on the bandgap. The findings elucidate the exceptional bandgap characteristics of this configuration, coupled with its ability to accommodate tailored thermal expansion coefficients and minimize thermal stress. By judiciously selecting materials and refining structural design, the study envisages the attainment of multiple objectives in thermal expansion properties and bandgap modulation. Such endeavors hold promise for enhancing the tunability and multifunctionality of the metamaterial, thereby advancing its utility across diverse applications.
