      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 ...

      Numerical simulation of injection mold filling for semi-solid materials 

      Ahmed, Alauddin; Alexandrou, Andreas N. (ASME, 1995)
      Processing of metals and metal matrix composites in the semi-solid state is an emerging new technology and is becoming increasingly popular. This method provides several advantages over the traditional liquid state processing ...

      Thermo-fluid modeling of direct chill casting of metal alloys using an inverse finite element method 

      Alexandrou, Andreas N.; Battisti, T. (Publ by Computational Mechanics Inc, 1992)
      Direct chill (DC) casting is used extensively in the production of wrought nonferrous metals and alloys, particularly in the aluminum industry. For alloys, a semi-solid region known as the “mushy zone” and defined by the ...
