Effect of compressive load on texture evolution and anisotropic behavior of dual-phase steel under biaxial loading in complete σ11-σ22 space

Journal of Materials Research and Technology, 2023
Advanced high strength steels (AHSS) are typically loaded in a multiaxial stress state during forming process and service. However, the deformation mechanism under multiaxial loading is not clarified, which limits the optimization of sheet metal forming.
