Title: An Improved Modeling of Friction for Extrusion Simulations

Abstract

Realistic representation of friction is important in extrusion simulations. Purposefully designed multi-hole die aluminum extrusion experiments showed that the conventional friction models, like the Coulomb and the shear friction models, are deficient to represent the boundary phenomena that occur during aluminum extrusion. Based on the observations, phenomenological and implementational improvements are made in the friction modeling.
