In this paper, we systematically proposed the strategy of tailoring strain delocalization to evade long-standing strength-ductility trade-off dilemma. The scientific contribution is define and, for first time, expand category localization into whole deformation process, including elastic lattice distortion, plasticity-relevant statistical behaviors (dislocation, twinning, shear/slip bands, necking, etc.), and crack-dependent damage accumulation. viewpoint that achieving synergy depends on delocalizing aforementioned localized strains. Using hierarchical materials as an example, design heterogeneous structure significantly influences in terms internal stress/strain (elastic stage), local evolution (plastic cracking (fracture stage). Relationships among microstructure, microscopic evolution, macroscopic mechanical properties are established. particular, assess their from perspective slip transfer, plastic stability, micromechanics, crack propagation. A methodological framework then suggested understand future using rapidly developed physics-based multi-dimensional computational models advanced situ characterization techniques.
