摘　　要：采用弹塑性有限变形问题的边界无法对板带轧制过程进行了模拟。计算中同时考虑了几何和材料双重非线性的影响,给出了轧制压力、摩擦力和前后张力的分布。计算结果与实验结果进行了比较,证明了本文给出的方法是正确的,为板带轧制过程的分析提出了一种有效而精确的方法。In this paper, the boundary element method of 3-dimensional elastoplastic finit deformation problems is used to simulate strip rolling process. In the calculation, both material and geometric nonlinearities are considered. The rolling pressure, friction, front tension and back tension distributions are given. The calculation results are similar with experiment results. It is oroved that the method given in this paper is correct and can be used to analyze strip rolling process accurately.
