在板料分析的基础上，开发了一套数值分析程序，用于计算复合材料板的各组成层在轧制过程中发生的应力和应变，这些应力和应变发生在覆层金属（如镀银磷青铜）的轧制过程中。将理想塑性模型和应变硬化模型的计算结果与实验结果进行了比较，发现应变硬化模型的计算结果与轧制力和轧制后构件层厚度的测量值吻合较好。该程序需要输入的数据包括轧辊半径、试样的初始厚度、初始包层厚度分数、折减比、轧辊与材料之间、组件层之间的摩擦系数以及前后张力。摩擦系数通过实测轧制力与板坯分析计算力的比较间接求得。实测摩擦系数随减径比和初始厚度的变化而变化，但与轧制速度无关。MST / 1334
A numerical analysis program, based on slab analysis, was developed to calculate the stresses and strains that occur in the component layers of a composite sheet in the roll bite during the fabrication of clad metal (e.g. silver clad phosphor bronze) by roll bonding. Results calculated using the perfect plastic and strain hardening models were compared with experimental results: the results obtained using the strain hardening model were found to be in better agreement with values of rolling force and thickness of component layers measured after roll bonding. The program requires input data such as roll radius, initial thickness of the specimen, initial cladding thickness fraction, reduction ratio, coefficients of friction between rolls and material and between component layers, and front and back tensions. The coefficients of friction were evaluated indirectly by comparison of the measured rolling force with that calculated using slab analysis. Measured coefficients of friction varied with reduction ratio and initial thickness, but were independent of rolling speed. MST/1334
