Pham and colleagues developed a polycrystalline lattice superstructure that exhibits shear-banding behavior similar to metallurgical crystal twins. Lu and his team investigated the hardening principle of inclusions and the strengthening mechanism of dual-phase lattice structures. By modifying crystal interfaces and introducing nanocrystals, researchers have controlled the deformation pattern and damage mechanism of lattice structures. Other studies have improved mechanical properties by manipulating contact between adjacent member elements, incorporating holes, and analyzing defect types. These failure mechanisms inform the design of new lattice structures with superior mechanical properties.
