Buckling initiation in layered hydrogels during transient swelling
Ilseng, Arne; Prot, Victorien Emile; Skallerud, Bjørn Helge; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2019)Subjected to compressive stresses, soft polymers with stiffness gradients can display various buckling patterns. These compressive stresses can have different origins, like mechanical forces, temperature changes, or, for ... -
Donnan Contribution and Specific Ion Effects in Swelling of Cationic Hydrogels are Additive: Combined High-Resolution Experiments and Finite Element Modeling
Zurzul, Natasa; Ilseng, Arne; Prot, Victorien Emile; Sveinsson, Hrafn Mar; Skallerud, Bjørn Helge; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2020)Finite element modeling applied to analyze experimentally determined hydrogel swelling data provides quantitative description of the hydrogel in the aqueous solutions with well-defined ionic content and environmental ... -
A Perturbation Analysis Approach for Studying the Effect of Swelling Kinetics on Instabilities in Hydrogel Plates
Ilseng, Arne; Skallerud, Bjørn Helge; Stokke, Bjørn Torger; Prot, Victorien Emile (Journal article; Peer reviewed, 2021)The onset of surface instability during diffusion-driven swelling of hydrogels depends on the kinetics of the swelling process. Here, we outline a perturbation analysis framework using a finite difference approach for ...
