Pham et al. [31] created a polycrystalline lattice superstructure that had multiple crystal interfaces, resulting in a failure shear-banding symmetrical to the twin boundary. This demonstrated that the shear-banding behavior in twin superlattice structure is similar to the sliding behavior in crystal twins in metallurgy. Lu et al. [32] studied the hardening principle of inclusions that hinder the movement of dislocations and compared it to the strengthening mechanism of the dual phase lattice structure. The controllability of the shear-banding path allowed for the control of the local deformation pattern of the lattice superstructure and the shear-banding damage mechanism. By changing the crystal interface, researchers [17][33] were able to suppress the propagation distance of the local shear-banding, significantly improving the platform stress and energy absorption efficiency of the lattice superstructure. Wu et al. [34] found that by introducing dislocation-free nanocrystals with a diameter of around 6 nm into the amorphous matrix, they could inhibit the transfer of local shear-bandings, greatly enhancing the material’s properties. Additionally, defect characteristics of microstructures were used as inspiration for lattice structure design. Vangelatos et al. [35][36] reported that the mechanical properties of lattice, such as specific strength and stiffness, were significantly enhanced by utilizing the contact between adjacent member elements of the lattice. Bhuwal et al. [37] controlled the evolution of local shear-bandings by introducing holes with different sizes, spatial orientations, and topological distribution characteristics into periodic lattice structures. Furthermore, Ref [38][39] established a multi-scale lattice structure calculation and analysis model of various defect types, studying the influence of spatial structural defects on the mechanical properties of lattice structures. These typical failure mechanisms derived from the deformation behaviors of microstructures are crucial for designing new lattice structures with excellent mechanical properties.
