An Experimental Study and Theoretical Analysis on the Asymmetric Rolling Mechanics Condition

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.
