Analytical approach to the cold-and-hot bond rolling of sandwich sheet with outer hard and inner soft layers

Cold roll bonding of multi-layered bi-metal laminate composites

“…With the objective of predicting the rolling force and torque, a few models have been devised for roll bonding of two or three layer systems [21][22][23][24][25][26][27][28]. These deal primarily with the cladding of metals.…”

“…The slab method of analysis was also used in another study wherein the numerical results obtained for silver clad phosphor bronze were compared with actual experimental results [22]. Further studies involved analysis of rolling of two layers or three layers bi-metal sheets without using a numerical method [23,24]. Other modeling work made use of the extended upper-bound method [25][26][27][28].…”

“…The signs of the terms containing coefficient of friction can be changed in Eq. (24) to calculate the stresses.…”

Effective parameters on bonding strength of roll bonded Al/St/Al multilayer strips

“…Their important role has been investigated by some researchers during last years [34][35][36][37]. Tzou et al [34][35][36] developed analytical models for sandwich roll bonding to indicate distribution of horizontal and shear stresses in contact length with changing of clad to sandwich thickness ratios, frictional states, total reduction in thickness and yield stress ratio. Hwang et al [38] proposed an analytical model to simulate effects of various rolling conditions like flow stress ratio, initial thickness ratio and total thickness reduction upon parameters such as bonding length and mean contact pressure.…”

A simulation study on the multi-pass rolling bond of 316L/Q345R stainless clad plate

“…Although some results of specific process parameters on the bonding strength were obtained, the experimental study is time-consuming and laborious. Tzou and colleagues 9,10 obtained the stress field of cold and hot bond rolling of unbounded sandwich plates by formulating an analytical model of the cold bond rolling of unbounded double-layer sheet. Hwang et al 11 analyzed the effects of various rolling conditions such as total thickness reduction and initial thickness ratio upon bonding factors such as the mean contact pressure and bonding length by proposing an extended analytical model.…”
