Simulation Of Frictional Conditions During Long Product Hot Rolling

Finite Element (FE) techniques have been increasingly used to model shape and microstructural evolution, engineering constraints (rolling load, torque, etc.) during hot rolling of both long and flat products in both off-line and more recently production environment. These models have often assumed a fixed isotropic coefficient of friction (COF) along the contact length with an average friction value of 0.3 as a Coulomb friction coefficient, according
