| 摘 要： | 本文利用密栅云纹法结合三次样条函数求导法,通过压剪实验,测量计算出压剪区内应变速率场及应力场。结果表明,水平应变速率及应力沿试件厚向分布不均;上下表面摩擦力大小不等;压剪区内存在着横贯变形区的大剪应力场。利用实验数据回归出异步条件下接触弧的摩擦系数表达式,并结合Nadai斜面压缩金属楔解建立了新的异步轧制压力模型。新模型与实际吻合较好。

| Abstract: | By means of the dense grid moire and the derivation with the third power spline function, the strain rate fields and the stress fields were obtained through a shearing compression experiment. Using the experiment data, the upper and lower surface friction factor functions s were gained. A new model was developed by Nadai's calculation of stres field in a coverging wedge-shape symmetricl channel and was compared with the Others' calculations. It is shown that the results of the new model agree well with those measured in the test. |
