J. Cent. South Univ. (2021) 28: 1316-1323 DOI: https://doi.org/10.1007/s11771-021-4699-5 Microstructure and anisotropy of mechanical properties in ring rolled AZ80-Ag alloy ZHANG Dong-dong(张冬冬)1...: The microstructure, anisotropy in tensile strength and tensile creep resistance of the ring rolled AZ80-Ag alloy were studied. The ring exhibited higher strength along rolling direction (RD) than......

, the shear fracture preferentially occurs as the stress anisotropy coefficient increases. Both the maximum tensile stress and equivalent maximum shear stress decrease as the stress anisotropy coefficient increases, which indicates that the greater the stress anisotropy coefficient, the higher the external loading required to propagate a new fracture. The numerical results obtained in this paper provide......
