| 摘 要： | 采用反射低分辨改进最大熵三维取向分布函数法(MMEMODF)和级数展开法(简ODF)，按照织构多晶体连续力学法(CMTP)，遵循Konchendoerfer模型，选择非二次型屈服函数来预估多晶体深冲IF钢板的塑性应变比R值．预估结果表明，MMEMODF低分辨织构计算法可以准确测算R值． |
| 关 键 词： | IF钢板 织构 塑性应变比 改进最大熵ODF |

| Abstract: | 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. |
| Keywords: | IF steel sheet texture plastic strain ratio modified maximum entropy method ODF |
