“…Both two and three dimensional functions were proposed to construct the kinematically admissible strain velocity fields. [19][20][21][22][23][24][25][26] The single and dual-stream functions are constructed in a way that the velocity vector at a point in the deformation zone is the tangential vector to the flowline passing through this point. It is assumed that the material flows along prescribed trajectories called flowlines or streamlines.…”

A new analytical model is presented that expresses kinematically admissible velocity fields in rolling processes. Opposed to conventional streamline approaches, the current model does not force the material to flow along the prescribed lines, but introduces a new coordinate that is constant over these lines, to prescribe a fixed component of the velocity in the rolling direction as a function of that coordinate and the coordinate along the rolling direction. The interaction between the rolls and the surface is incorporated in the model via two scalar parameters which depend on the friction conditions between the roll and the sheet, and the properties of rolled material. The scalar parameters can be tuned with experimental observations of deformation flow across the thickness. The modelled material flow does not reveal significant deviation from the one calculated by streamlines. The obtained analytical expressions for the velocity gradient tensor components combined with polycrystal plasticity models enables the prediction of the through-thickness texture evolution for various friction conditions.

In order to study the effects of work roller diameter on shape of strip in cold strip rolling process, the ANSYS/LS-DYNA software was employed to simulate rolling process of 2mm thickness stainless steel. It is found that the average of stress decrease along with the increasing diameter of the work roller.But this variation is about 1%.The stressstrain curve go more steady and the shape of strip become better along with the decreasing of the work roller diameter. In this paper the three kinds of rolling process will produce tiny waves edge. The waves edge was the most obvious when the work roller diameter is 60mm.

“…Evidently, the method proposed by Yang is not capable of solving many other problems such as the conical, elliptic and hyperbolic dies that have non-zero slopes at entrance or exit. An arbitrary shapes of rigidplastic boundaries was proposed by Wang et al (2008) to solve the problem of the width spread of rolling forming and the further work for the analyzing of the arbitrary profile of dies is extended in this paper.…”
