Abstract
In this research, a mathematical model for the cold drawing of bilayered strip is presented by the upper bound method. In terms of effective process parameters such as drawing power, drawing force, layer reductions, and bonding strength of the bimetal strip, the effect of total relative thickness reduction has been investigated using the upper bound theorem. Also, bonding strength is calculated using the method. In order to verify the theoretical model, a series of experiments on bilayer strip drawing are implemented by aluminum and mild steel material strips. Through the study, it can clearly been concluded that the presented analytical approach is applicable for simulating and estimating the cold drawing process of the bilayer sheets and it is able to offer a good knowledge through producing the bimetal sheets.
