Numerical modelling of gold-roll bonding of clad metal sheets

Abstract

An analytical model based on the rigid-plastic finite-element formulation for slightly compressible materials is newly proposed to examine the bonding behavior at the roll gap during clad metal sheets rolling. The interfacial elements inserted between the two metals, which are characteristic of the shear-susceptible deformation with the help of the shear factor in the expression of effective strain rate, are used to model the relative slidding at the interface. It is found that the proposed method is applicable to the simulation of clad metal sheets rolling.
