Pham et al. [31] developed a polycrystalline lattice superstructure that had multiple crystal interfaces and exhibited failure shear-banding symmetrical to the twin boundary, similar to sliding behavior in metallurgy. Lu et al. [32] compared the hardening principle of inclusions that hinder dislocation movement with the strengthening mechanism of dual phase lattice structures. The controllability of the shear-banding path allows for control over the deformation pattern and damage mechanism of lattice superstructures. Researchers [17][33] improved the stress platform and energy absorption efficiency by changing the crystal interface to suppress local shear-banding propagation distance. Wu et al. [34] found that adding dislocation-free nanocrystals to an amorphous matrix inhibited local shear-banding transfer and enhanced material properties. Lattice structure design can be inspired by defect characteristics of microstructures. Vangelatos et al. [35][36] enhanced specific strength and stiffness of lattices by utilizing contact between adjacent member elements. Bhuwal et al. [37] controlled local shear-banding evolution through the introduction of holes with varying characteristics into periodic lattice structures. Multi-scale lattice structure calculation and analysis models were established in Ref [38][39] to study the influence of spatial structural defects on mechanical properties. These typical failure mechanisms derived from microstructure deformation behaviors are crucial for designing new lattice structures with excellent mechanical properties.
