Abstract
Metallic materials exhibit structural and performance anisotropy at various scales, including the crystal structure, microstructure, and bulk levels. The anisotropy influences how stress and strain distribute within the material. The localized stress concentration is closely related to deformation and several failure mechanisms. A systematic exploration of the anisotropy can deepen our understanding of stress concentration and material failure, and guide the design of high-performance materials tailored for specific applications. Additionally, this work supports sustainable development by enhancing the service life and recyclability of metallic materials—an increasingly critical priority in materials science.....
