    Abstract: 摘要
    The elastic-plastic boundary is known as the interface that the plate materials switch form elastic to plastic by the compression of rolling by rolls.For the forming theories, the elastic-plastic boundary define the area of the plastic deformation that caused by the rolling of the plate materials.
    The plastic deformation boundary discussed by theory of plastic forming usually ignores the effect of the elastic deformation and presented by the low order polynomials. It is also hard to be observed in practice of rolling. This research is subjected to the consideration of elastic deformation and focus on the change of the elastic-plastic boundary during the forming by the finite-element software, MSC. Marc. It is expected to get the practical model of the boundary of plastic deformation. Through mathematical formula to resolve the plate rolling process, Material Internally generated elastic-plastic boundary, Inform them about the plate rolling process generated distribution of elastic-plastic boundary, The following parameters are discussed in this thesis: the friction coefficient, the ratio of reduction, the ratio of velocity and the ratio of roll radius and the impact on the curvature of the plate after rolling.
