Abstract Based on the models of continues mechanics of textured polycrystals (CMTP) and Kochendőrfer in which the quadric yield function form is employed, the
plastic strain ratio (R-values) of
polycrystalline metal (deep-drawing IF steel sheets) is calculated by
the approaches of modified maximum
entropy method (MMEM) of low-resolution texture analysis and harmonic
method. The computed results
indicate that the MMEM of low-resolution texture analysis can predict
the R values accurately.
