Øvreeide, Ingrid Haga; Szydlak, Renata; Luty, Marcin; Ahmed, Husnain; Prot, Victorien Emile; Skallerud, Bjørn Helge; Zemła, Joanna; Lekka, Małgorzata; Stokke, Bjørn Torger (Journal article; Peer reviewed, 2021)Aqueous microgels are distinct entities of soft matter with mechanical signatures that can be different from their macroscopic counterparts due to confinement effects in the preparation, inherently made to consist of more ... -
Palatal implant surgery effectiveness in treatment of obstructive sleep apnea: a numerical method with 3D patient-specific geometries
Liu, Hongliang; Moxness, Mads Henrik Strand; Prot, Victorien Emile; Skallerud, Bjørn Helge (Journal article; Peer reviewed, 2018)Obstructive sleep apnea (OSA) affects a large percentage of the population and is increasingly recognized as a major global health problem. One surgical procedure for OSA is to implant polyethylene (PET) material into the ... -
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 ... -
Radiation therapy and training effects on the mechanical performance of bone
Auestad, Martin Fridheim (Master thesis, 2021)Med stadig stigende forventet levealder oppstår nye aldersrelaterte utfordringer. Eksponering for både osteoporotiske brudd og kreft øker med alder, og flere tilfeller oppdages siden ny teknologi for medisinsk undersøkelse ... -
Reverberation suppression with dual band imaging in medical ultrasound
Brende, Ole Martin (Doctoral thesis at NTNU;2016:194, Doctoral thesis, 2016)Sammendrag: Undertrykkelse av reverberasjonsstøy med to-frekvent medisinsk ultralyd - Ultralyd er en velkjent og velbrukt metode for avbildning i medisin. Det er mange grunner til dette. Ultralydutstyr er billig å ... -

Surface Wrinkling with Memory for Programming Adhesion and Wettability
Wang, Feng; Xiao, Senbo; Luo, Sihai; Fu, Yuequn; Skallerud, Bjørn Helge; Kristiansen, Helge; cui, mengkui; zhong, chao; Liu, Siqi; Zhuo, Yizhi; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2023)Modulating surface wrinkling is important for a variety of engineering applications. It has been known for more than two decades that the wavelength of surface wrinkles occurring in a metal film–soft polymer system scales ... -
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 ... -
Tension behaviour of HNBR and FKM elastomers for a wide range of temperatures
Ilseng, Arne; Skallerud, Bjørn Helge; Clausen, Arild Holm (Journal article; Peer reviewed, 2016)This article presents uniaxial tension tests of three different elastomer compounds commonly applied as seal materials in the oil and gas industry. The tests were performed at five different temperatures, ranging from −20 ... -
