Plastic Strain Ratio Calculation of Metal Sheet from Low-Resolution Texture Analysis
从低分辨织构计算金属板材的塑性应变比

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. The computed results indicate that the MMEM of low-resolution texture analysis can predict the R values accurately.
