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.

  • This work proposes to use a special upsetting test and an optimal direct extrusion one performed to identify the constitutive equation of the material behavior and the friction coefficients directly from the load-stroke curves. The proposed friction test has the advantage to permit to take into account contact phenomena corresponding to new specimen surfaces created during a real bulk cold forming process. A lot of numerical simulations are made with the commercial software FORGE2 in order to study the influence of some design and process parameters. Different friction laws will be identified starting from the classical Coulomb and Tresca ones.more » All the parameter identifications are made using the Inverse Analysis principle.« less
  • Two-sided friction stir riveting (FSR) by extrusion is an innovative process developed to rapidly, efficiently, and securely join dissimilar materials. This process extends a previously developed one sided friction stir extrusion process to create a strong and robust joint by producing a continuous, rivet-like structure through a preformed hole in one of the materials with a simultaneous, two-sided friction stir spot weld. The two-sided FSR by extrusion process securely joins the dissimilar materials together and effectively locks them in place without the use of any separate materials or fasteners. Lastly, in this paper we demonstrate the process by joining aluminummore » to steel and illustrate its potential application to automotive and aerospace manufacturing processes.« less
  • In this paper we present a method to determine the frontlines inside the container and inside the extrusion die based on a steady state velocity field. Using this velocity field the convection equation is solved with a SUPG stabilized finite element method for a variable that represents the time it takes from the initial front to a certain point in the domain. When iso-lines in this field are plotted the development of fronts can be tracked. Extrusion experiments are performed with aluminium billets cut in slices. When extrusion is stopped the billet and extrudate are removed from the container andmore » cut in half in the extrusion direction, copper foils between the slices show the frontlines. These lines show good agreement with the iso-lines from the numerical solution of convection equation.« less
  • There has been a considerable advancement in technology available for providing a barrier system in the containment and storage of waste materials. Natural soil liners several feet in thickness have been augmented by factory-produced, synthetic materials that have permeability coefficients several orders of magnitude lower than any natural soil system. To carry the systems approach one step farther, engineers use multiple layers of synthetics separated at times by layers of clay offering a redundant composite barrier to protect the groundwater. Each geosynthetic material offers its own unique contribution to the system based upon its physical characteristics. Co-extrusion -- the processmore » of combining two or more materials into a single product, through a single process -- is now revolutionizing the liner industry.« less
  • Hydrostatic extrusion, as a quite rarely applied technique, is used for the deformation of the Zr-based metallic glass/porous tungsten phase composite prepared by pressure infiltration. The fracture strength increases from 1852 MPa for the as-cast composite to 2112 MPa for the as-extruded composite. An apparent work hardening behavior was also observed in the as-extruded composite. The improved mechanical properties of the as-extruded composite are proposed to contribute to the stable interface between the metallic glass phase and the tungsten phase and the high dislocation density of the tungsten phase.
