Analysis on uncertainty of plastic strain ratio-r ratio of metallic sheet;

Effects of electric field annealing on plastic strain ratio(r value)of IF(interstitial free)deep drawing steel sheet were studied by mean of tensile test.

Based on the models of continues mechanics of textured polycrystals (CMTP) and Kochend(?)rfer 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.
