Dynamics of swelling and drying in a spherical gel (2015, unknown): “For relatively small volume changes, the dynamics of swelling have been studied using both simple linear models [24–30] and fully non-linear models [4, 6, 31, 32], but no study has yet combined the fully nonlinear and transient mechanics of swelling with the extreme volume changes that are one of…”
A nonlinear, transient finite element method for coupled solvent diffusion and large deformation of hydrogels (2015, background): “For either poroelasticity or hydrogels, the transient response can often be decomposed into three stages (Rice and Cleary, 1976; Yoon et al., 2010; Bouklas and Huang 2012): the instantaneous response at t 0→ , the transient evolution, and the equilibrium or steady state as t → ∞.”
Mechanics and chemical thermodynamics of phase transition in temperature-sensitive hydrogels (2011, background): “A recent study has compared the field theory and experiments concerning the kinetics of swelling (Yoon et al., 2010).”
Hygrobot: A self-locomotive ratcheted actuator powered by environmental humidity (2018, background): “1B, ts increases with h (2), implying that the hygroexpansion occurs as water molecules diffuse into the active layer (26).”
