摘要： <正> In this paper,such a new lateral displacement function is proposed that the lateral flow velocity is con-tinuous at the entry and the exit of deformation zone.A new kind of finite strip method—the third powerB-spline finite strip method—is put forward to simulate strip rolling process.Front and back tension stressesare formulated.The computed results of the transverse distributions of the front and back tension stresses areclose to the experimental results.The paper lays a foundation for further analysing the three-dimensionalstresses and deformations of strip rolling.
