      An inverse finite element method with an application to extrusion with solidification 

      Alexandrou, Andreas N.; Anturkar, N. R.; Papanastasiou, T. C. (1989)
      The flow and solidification of planar jets are analysed by means of an efficient inverse isotherm finite element method. The method is based on a tessellation that is constructed by isotherms as characteristic co‐ordinate ...

      Isothermal extrusion of non-dilute fiber suspensions 

      Papanastasiou, T. C.; Alexandrou, Andreas N. (1987)
      The extrusion of a rod-like fiber suspension is a Newtonian solvent, as a first step to the fast and inexpensive production of composite materials, is investigated. The analysis is carried out by means of an integral ...

      Laminar jets of Bingham-plastic liquids 

      Ellwood, K. R. J.; Georgiou, Georgios C.; Papanastasiou, T. C.; Wilkes, J. O. (1990)
      The steady and transient behavior of jets generated by circular and slit nozzles are analyzed by the Galerkin finite-element method with free-surface parametrization and Newton iteration. A novel constitutive equation is ...
