一、前言轧制理论的目的在于建立外加载荷与被轧制条料的机械性能之间的关系。在板料轧制中,有关完全刚塑性条料或理想加工硬化条料的滑移线场和应力分布,目前已有许多理论性的研究。然而,这些理论分析中所用假设的合理性到目前为止还只是部分得到了验证。为了求得轧制压力,虽然已进行了一些实验,但其结果和相应的实际应力状态之间的关系还没有得到充分研究。造成这种情况的主要原因似乎是目前还没有研究出一种合适的方法来测量这种
I. Introduction The purpose of rolling theory is to establish the relationship between the applied load and the mechanical properties of the strip to be rolled. In sheet metal rolling, there are many theoretical studies on the slip field and stress distribution of completely rigid plastic strips or ideal work-hardening strips. However, the rationality of the assumptions used in these theoretical analyzes has so far been only partially verified. In order to obtain the rolling pressure, although some experiments have been carried out, the relationship between the result and the corresponding actual stress state has not been sufficiently studied. The main reason for this seems to be that no suitable method has been developed to measure this
