摘要：Edge cracking is a commonly observed phenomenon during the cold rolling process of the silicon steel strip which may cause the rupture of strip and reduce the product quality and productivity. In this work, the damage behavior and edge cracking of steel strip in cold rolling is analyzed based on a shear modified Gurson model. Taguchi experimental design method is used to analyze the effects of reduction ratio, roll diameter, tension, friction coefficient on the initiation and propagation of edge cracks. The analysis results reveal that the possibility of edge crack for silicon steel increases with the increasing of reduction ratio, tension, friction coefficient and the decrease of roll diameter.
