      Dynamic responses in nanocomposite hydrogels 

      Loizou, Elena; Butler, P.; Porcar, L.; Schmidt, G. (2006)
      The shear response of a series of polymer-clay gels has been investigated by means of rheology and small-angle neutron scattering (SANS). The gels have the same composition by mass but different polymer molecular weights ...

      Three dimensional flow of thixotropic materials in a channel with a sudden expansion using a phenomenological constitutive relation 

      Alexandrou, Andreas N. (Affiliation: WPI, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.WPI, Worcester, United States, 1996)
      A constitutive relation is proposed that is capable of predicting a wide range of experimental rheological behavior depending on the proper choice of the parameters. The model represents the otherwise discontinuous Bingham ...
