Finite Element Method tor Three-Dimensional Viscoelastic Extrusion

  • O. Wambersie
  • M. J. Crochet


We have developed a time-marching finite element method for solving three-dimensional extrusion which makes use of the conjugate gradient method. The algorithm, initially devoted to generalized Newtonian fluids, has been extended to viscoelastic flow. We briefly explain the method and show some applications.
