Boundary-Element Analysis of Forming Processes

  • Chapter
Numerical Modelling of Material Deformation Processes

Abstract

The numerical analysis of problems in forming can be accomplished by a variety of techniques; one has finite differences, finite elements, boundary elements, and other methods. Each method has some advantage over the others in certain classes of problems, and here we review the use of boundary-element methods in some slow Newtonian and non-Newtonian (or rheological) forming problems. The term non-Newtonian fluid means a material not described by the Navier-Stokes equations. The simplest non-Newtonian fluid class includes materials where the viscosity depends on the scalar invariants of the rate-of-deformation tensor D. In some cases metal deformation can be so modelled (Karabin and Smelser 1989). A much greater challenge is posed by fluids with memory (or viscoelasticity) and part of this chapter is devoted to this category of materials; molten plastics are perhaps the most important examples of viscoelastic fluids.
