AXITOM: A Python package for reconstruction of axisymmetric tomograms acquired by a conical beam
Olufsen, Sindre Nordmark (Journal article; Peer reviewed, 2019)The ability to picture the internals of a body in a non-invasive way is vital for both diagnostics and research in a broad range of fields. Tomography is the imaging of body sections, typically acquired from projections ... -
Experimental and numerical study of dilation in mineral filled PVC
Olufsen, Sindre Nordmark (Doctoral theses at NTNU;2020:388, Doctoral thesis, 2020)This thesis addresses the link between applied load and dilation caused by void growth in mineral-filled PVC employing both experimental and numerical techniques. The influence of stress triaxiality and strain rate on the ... -
Impact of stress triaxiality, strain rate, and temperature on the mechanical response and morphology of PVDF
Hund, Jonas; Granum, Henrik Møgster; Olufsen, Sindre Nordmark; Holmström, Petter Henrik; Johnsen, Joakim; Clausen, Arild Holm (Journal article; Peer reviewed, 2022) -
Influence of constituent particles on fracture of aluminum alloys under high-triaxiality loading
Dæhli, Lars Edvard Blystad; Olufsen, Sindre Nordmark; Kristensen, Tore Andre; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2023)Single-edge notch bending tests are conducted to study the influence of constituent particles on the fracture resistance of aluminum alloys 6061, 6063, and 6110 under high-constraint loading conditions. The alloys are ... -
Influence of loading conditions on the tensile response of degraded polyamide 11
Olufsen, Sindre Nordmark; Nygård, Per; Ines Teixeira Pais, Catarina; Perillo, Giovanni; Hopperstad, Odd Sture; Clausen, Arild Holm (Peer reviewed; Journal article, 2021)The chemically induced embrittlement of polyamide 11 (PA11) has been the subject of a considerable research effort to understand and predict the degree of embrittlement based on the material's intrinsics. However, the ... -
Influence of stress triaxiality and strain rate on stress-strain behaviour and dilation of mineral-filled PVC
Olufsen, Sindre Nordmark; Clausen, Arild Holm; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2019)The influence of stress triaxiality and strain rate on the tensile behaviour of mineral-filled polyvinyl chloride (PVC) is investigated in this paper. Axisymmetric notched tensile specimens with notch radius equal to 20 mm, ... -
Modelling of fluid-structureinteraction with a cartesian gridmethod: Application to shock tube simulations
Resell, Anders Aamodt (Master thesis, 2022)Abstract will be available on 2025-06-11 -
Numerical Analysis of Primary Stability on Cementless Hip Prostheses
Olufsen, Sindre Nordmark (Master thesis, 2012)Since the first Total Hip Arthroplasty (THA) performed in the 60's, it has been regarded among the most successful surgical procedures. When an un-cemented hip prosthesis is employed, the prosthesis is impacted into a ... -
RECOLO: A Python package for the reconstruction of surface pressure loads from kinematic fields using the virtual fields method
Olufsen, Sindre Nordmark; Kafumann, Rene; Fagerholt, Egil; Aune, Vegard (Peer reviewed; Journal article, 2022) -
Reconstruction of surface pressures on flat plates impacted by blast waves using the Virtual Fields Method
Kaufmann, Rene; Olufsen, Sindre Nordmark; Fagerholt, Egil; Aune, Vegard (Peer reviewed; Journal article, 2023)An accurate description of surface pressure loads imposed by blast waves is crucial for the design of the next generation of blast-resistant structures. However, experimental techniques for non-intrusive, full-field surface ... -
A technique for in situ X-ray computed tomography of deformation-induced cavitation in thermoplastics
Olufsen, Sindre Nordmark; Tekseth, Kim Robert Bjørk; Breiby, Dag Werner; Clausen, Arild Holm; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2020)Deformation-induced cavitation influences the mechanical response of polymeric materials, but acquiring in situ measurements of the spatial evolution of cavities has typically necessitated the use of synchrotron radiation ... -
X-ray computed tomography investigation of dilation of mineral-filled PVC under monotonic loading
Olufsen, Sindre Nordmark; Clausen, Arild Holm; Breiby, Dag Werner; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2019)The deformation-induced dilation of mineral-filled polyvinyl chloride (PVC) is investigated by means of polychromatic X-ray absorption tomography (XCT). Axisymmetric notched tensile specimens are strained to prescribed ... -
