A Study on the Plastic Deformation During Rolling by Visioplasticity Method
-
摘要: 本文用视塑性法研究轧制过程金属塑性变形特性。通过网格法试验得到纯铅轧制时的流线,并对变形率为21%的薄轧件(8×60mm)之变形特性进行了全面分析,还对变形率为8.8%的厚轧件(40×30mm)作了初步计算。Abstract: Using Visioplasticity method,the flow and deformation of rolling process have been studied.The main conclusions are as follows:
1. Visioplasticity method is usefal for analyzing flow and deformation of metals during rolling.
2. The deformation and flow of metal are not homogeneous.
3. Correct results can be obtained if there is suitable method to determine the flow lines.
