Pham et al. [31] developed a polycrystalline lattice superstructure comprising multiple crystal interfaces, which exhibited failure shear-banding symmetrical to the twin boundary. This phenomenon is comparable to sliding behavior observed in metallurgical crystal twins. Lu et al. [32] explored the hardening principle of inclusions that inhibit dislocation movement and the strengthening mechanism of dual phase lattice structures. The shear-banding path of lattice superstructures can be controlled, enabling control over their deformation pattern and damage mechanism. Researchers [17][33] improved the stress platform and energy absorption efficiency of lattice superstructures by altering crystal interfaces to suppress local shear-banding propagation distance. Wu et al. [34] found that introducing dislocation-free nanocrystals into an amorphous matrix inhibited local shear-banding transfer and significantly enhanced material properties. Additionally, defect characteristics of microstructures inspired lattice structure design, such as using contact between adjacent member elements to enhance specific strength and stiffness [35][36], or controlling local shear-banding evolution through holes of varying sizes, spatial orientations, and topological distribution in periodic lattice structures [37]. Multi-scale lattice structure calculation and analysis models have been established to study the influence of spatial structural defects on mechanical properties [38][39]. These typical failure mechanisms derived from microstructure deformation behaviors are crucial for designing new lattice structures with excellent mechanical properties.
