Abstract: This paper presents a new engineering utility method (strip element method) simulating 3-dimensional stresses and strain rates of strip rolling. For cold strip rolling on a 4-h mill, the computed results of the rolling pressure, the 2-directional friction stresses and the front and the front and back tension stresses by the method are close to the experimental results, which proves that it is feasible using the method to simulate strip rolling process. Compared with 3-dimensional finite differences method, finite element method and boundary element method, the method has the merits of computing simplicity, economy and utility.
