The average texture over thickness was measured by the Schulz reflection method for determining one quadrant of pole figure of aluminum sheet 1100-H14. The texture measured is represented by a three-dimensional orientation distribution function. Yield locus and r-value are calculated using the theory developed by Bishop and Hill, in which an orientation distribution function is used as a volume fraction of certain orientated crystals. A chain of the measurement and calculations is executed by the micro- and large-computer 'quasi-on-line'. The calculated yield locus is close in shape to that measured by the biaxial compression test except a deviation based on Bauschinger effect. The calculated directional variations of stress in some strain or stress states and of r-value are in good agreement with observed ones.
