  • Dolbow, John E.; Fried, Eliot; Ji, Huidi (Department of Theoretical and Applied Mechanics (UIUC), 2004-01)
    We present a theory for the chemically-induced volume transitions of hydrogels. Consistent with experimental observations, we account for a sharp interface separating swelled and collapsed phases of the underlying polymer ...

  • Ji, Huidi; Mourad, Hashem; Fried, Eliot; Dolbow, John E. (Department of Theoretical and Applied Mechanics (UIUC), 2004-12)
    We present a continuum model for thermally-induced volume transitions in stimulus-responsive hydrogels (SRHs). The framework considers the transition as driven through the motion of a sharp interface separating swollen and ...

  • Dolbow, John E.; Fried, Eliot; Ji, Huidi (Department of Theoretical and Applied Mechanics (UIUC), 2004-06)
    We present a strategy for obtaining numerical solutions to a system of nonlinear, coupled evolution equations describing volume transitions in stimulus-responsive hydrogels (SRHs). The theory underlying our sharp-interface ...
