Constrained Hydrogel swelling in Biological Sensors: A Finite Element Method Approach
Sveinsson, Hrafn Mar (Master thesis, 2012)Material models has been developed for anionic and/or cationic hydrogels, with a simulation framework implemented in MATLAB and the finite element software ABAQUS. The geometry of the simulations is a hemispheroidal hydrogel, ... -
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 ... -
Swelling of a hemi-ellipsoidal ionic hydrogel for determination of material properties of deposited thin polymer films: an inverse finite element approach
Prot, Victorien Emile; Sveinsson, Hrafn Mar; Gawel, Kamila; Gao, Ming; Skallerud, Bjørn Helge; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2013)Selective deposition of polymers at the surface of an ionic hydrogel is conventionally used to tailor properties of the composite material for application in for instance drug release and cell encapsulation. Here we describe ...
