摘要: Abstract The effect of the basal texture on mechanical behaviour AZ31B magnesium alloy sheet is studied numerically using a recently developed Elastic Visco-Plastic Self-consistent (EVPSC) model, in which both slip and twinning contribute to plastic deformation. We simulate uniaxial tension within plane starting textures having poles tilted at varying degrees from normal direction. It found that increasing tilt angle increases uniform strain, but decreases 0.2% proof strength R -value. metal forming further assessed by calculating limit strain under in-plane tension. demonstrated dramatically with decreasing intensity texture. numerical results are be good qualitative agreement experimental observations.
