Prediction of the rolling texture evolution in FCC metals is controlled by interaction laws, deformation mechanisms and definition of the lattice spin. The coupled effect of these three factors on the FCC rolling texture evolution is hereby analyzed using the viscoplastic phi-model. Without the Eshelby theory, this model yields an interaction law spanning predicted results from the upper to lower bound ones by varying a scalar weight parameter phi (0 < phi < 1). In this work, two definitions of the lattice spin, the mathematical analysis (MA) and the plane-strain analysis (PSA), are considered in the phi-model. The influence of the MA and PSA definitions on the FCC rolling texture evolution is deeply analyzed in conjunction with twinning and grain interaction strength, from a stiff to a more compliant interaction.
