      One-point modelling of rapidly deformed homogeneous turbulence 

      Reynolds, W. C.; Kassinos, Stavros C. (1995)
      Turbulent stresses introduced by Osborne Reynolds do not, by themselves, provide an adequate tensorial base for one-point modelling of rapidly distorted turbulence because they do not carry critical information about the ...

      The simultaneous use of 4×4 and 2×2 bilinear stress elements for viscoelastic flows 

      Georgiou, Georgios C.; Crochet, M. J. (1993)
      Mixed finite elements for viscoelastic flows based on a 4×4 sub-linear interpolation for the extra stress components satisfy the Babuska-Brezzi condition and are highly stable. They have been proved to be quite satisfactory ...

      Structural effects of crosslinking a biopolymer hydrogel derived from marine mussel adhesive protein 

      Loizou, Elena; Weisser, J. T.; Dundigalla, A.; Porcar, L.; Schmidt, G.; Wilker, J. J. (2006)
      In an effort to explore new biocompatible substrates for biomedical technologies, we present a structural study on a crosslinked gelatinous protein extracted from marine mussels. Prior studies have shown the importance of ...

      Systems of hyperbolic conservation laws with memory 

      Christoforou, Cleopatra (2007)
      Global weak solutions of bounded variation to systems of balance laws with non-local source are constructed by the method of vanishing viscosity. Suitable dissipativeness assumptions are imposed on the source terms to ...

      A timestepper approach for the systematic bifurcation and stability analysis of polymer extrusion dynamics 

      Kavousanakis, M. E.; Russo, L.; Siettos, C. I.; Boudouvis, Andreas G.; Georgiou, Georgios C. (2008)
      We discuss how matrix-free/timestepper algorithms can efficiently be used with dynamic non-Newtonian fluid mechanics simulators in performing systematic stability/bifurcation analysis. The timestepper approach to bifurcation ...

      Uniaxial and biaxial mechanical behavior of human amnion 

      Barocas, V. Η; Oyen, M. L.; Cook, R. F.; Stylianopoulos, T.; Calvin, S. E.; Landers, D. V. (2005)
      Chorioamnion, the membrane surrounding a fetus during gestation, is a structural soft tissue critical for maintaining a successful pregnancy and delivery. However, the mechanical behavior of this tissue membrane is poorly ...
