  • To eliminate the residual stress formed during the process of Al board cold rolling, the distribution of stress in the deformation region was stimulated by elas-plastics large deformation finite element analysis. Analyzing the effects towards residual stress from different rolling loadcase, the value of cold rolling residual stress caused by different compress was gotten; Analyzing parameters stretching toward different rolling loadcase board, the effect of the residual stress elimination influenced by stretching force and stretching deformation was figured out. The simulative results show that the method of the proper stretching (about 2%) can evenly and partly eliminate the residual stress, reduce the effect toward the following manufacture induced by the residual stress.
