A novel model based on quartic velocity field for hot rolling force of aluminum alloy thick plate

A quartic flow velocity field is proposed to establish an online rolling force predicting model for the rolling process of aluminum alloy thick plates. The solving process relies on the energy method. Through comparing the calculated rolling force data and the actual rolling force, it is found that this model can be applied for online rolling force predicting. The assumption of the metal flow velocity in this paper is a beneficial attempt at the plastic mechanics.
