Results indicate the local high point height and additional tension stress of rolled strip are proportional to local high point initial height of strip, decrease as rolling reduction ratio increases.
In the paper, the elastoplastic boundary element method (BEM) of the initial strain is worked at calculating parameters of flat rolling of plate and strip.
