Cruciform specimen is utilized to study the influence of equi-biaxial stress state on the plastic strain response of AA7075-T651 alloy until fracture. The failure ductility as a function of stress state is evaluated using non-contact digital image correlation technique. The distinct biaxial deformation behavior in contrast to uniaxial response is attributed to strong crystallographic texture developed during prior hot-rolling reduction. The weakening of initial brass texture upon equi-biaxial deformation is also evident from the orientation distribution analysis. Increased activity of grain boundary assisted cracking due to increased stress triaxiality due to biaxial loading is evident, when compared to uniaxial stress state. © 2021 Elsevier B.V.
