Descrição: A finite element method to simulate coupled thermal viscous coextrusion is presented, with a power‐law viscosity function obtained from viscometric data on rubber composites. It combines, by successive substitution iterations, some well‐known schemes, such as streamline integration for updating interfaces and Lagrange‐Galerkin treatment of the energy equation. Some details of the implementation are discussed. The method is then applied to a comparison of two pre‐forming plates for the dual tuber head extruder of Farrel Corporation. Both the normal stress and the temperature at the interface suggest that the presence of a deflector deteriorates the adherence properties. This prediction is in agreement with operational experience.
