    Abstract

    The current development of science and technology has put forward higher requirements for the versatility of materials. In this paper, a bending-oriented joint-bonded triangular cell lattice metamaterial (JTCLM) with triangular lattice was studied, and the influencce of geometrical parameters on the band gaps of JTCLM unit cell was discussed. The results show that the band gaps will be generated when the JTCLM cell has curved curvature, and the geometrical parameters of the microstructure have significant influence on the band gap of the JTCLM lattice composite. The results provide a theoretical basis for the design of metamaterials with binocular objects of thermal expansion and band gaps. Through reasonable material selection and shape design, it is expected to achieve a win-win situation with specific expansion properties and band gap design, so that the material has better tunability and versatility.
