R value of AZ31 plate via their influence on twinning activity.
We show that any highly textured metal that deforms predominantly by deformation twinning can exhibit a negative lateral strain ratio under uni-axial loading. Theoretical calculations of lateral strains caused by tension twinning on the

plane in a magnesium single crystal predicts this behavior, and we verify this by direct measurements of lateral strains in highly textured commercial magnesium alloy AZ31 deformed in uniaxial compression. The R values of AZ31 plate compressed in the rolling direction at −100
°C and 25
°C show negative values at compressive strain up to ∼0.03, and increase with strain and temperature. These evolution trends of
