چکیده انگلیسی
The multiaxial yield and plastic flow behavior of Ti-6Al-4V manufactured in two orientations via laser powder bed fusion (L-PBF) additive manufacturing was investigated. The mechanical properties of L-PBF Ti-6Al-4V were evaluated under uniaxial tension, plane strain tension, pure shear, and combined tension/shear loading. The mechanical behavior was found to be stress state dependent and slightly anisotropic. A plasticity model, consisting of a Hill 1948 anisotropic yield criterion, associated flow rule, and an isotropic hardening law was calibrated and used to describe the yield and plasticity behavior of this material. Validation of the plasticity model under multiaxial stress states demonstrated that the model was able to predict the stress state dependent anisotropic plasticity behavior of this material.
