      Compression molding of semi-concentrated fiber suspensions: Flow and fiber orientation 

      Ahmed, Alauddin; Alexandrou, Andreas N. (Publ by ASME, 1993)
      The focus of this paper is compression molding of semi-concentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...

      Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation 

      Barocas, V. Η; Stylianopoulos, T.; Bashur, C. A.; Goldstein, A. S.; Guelcher, S. A. (2008)
      The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...

      Injection molding of dilute and semi-dilute fiber suspensions 

      Alexandrou, Andreas N.; Ahmed, Alauddin (Publ by ASME, 1992)
      The focus of this paper is unsteady flow of semi-dilute fiber suspensions in complex geometries. These flows are typical of injection molding problems in which the raw material in granular form, usually plastic resin mixed ...

      Microstructure-based, multiscale modeling for the mechanical behavior of hydrated fiber networks 

      Barocas, V. Η; Chandran, P. L.; Stylianopoulos, T. (2008)
      A multiscale formulation is derived for the mechanics of a dilute fiber network microstructure, as occurs in in vitro reconstituted collagen gels, to accommodate the deterministic solution of a uniform-stress condition in ...
