【Abstract】

<正>A dislocation-density based crystalline plasticity model for dislocation transmission and pile-ups at grain boundaries and a microstructural failure criterion have been developed to determine optimal grain and grainboundary (GB) distributions for significantly improved ductility and fracture toughness in crystalline materials.Specialized finite-element method-
