  • Kohler, Felix; Gagliardi, Luca; Pierre-Louis, Olivier; Dysthe, Dag Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Growing crystals form a cavity when placed against a wall. The birth of the cavity is observed both by optical microscopy of sodium chlorate crystals (NaClO3) growing in the vicinity of a glass surface, and in simulations ...
  • Renard, Francois; McBeck, Jessica Ann; Cordonnier, Benoit; Zheng, Xiaojiao; Kandula, Neelima; Sanchez, Jesus Rodriguez; Kobchenko, Maya; Noiriel, Catherine; Zhu, Wenlu; Meakin, Paul; Fusseis, Florian; Dysthe, Dag Kristian (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Advances in triaxial compression deformation apparatus design, dynamic X-ray microtomography imaging, data analysis techniques, and digital volume correlation analysis provide unparalleled access to the in situ four-dimensional ...
  • Kandula, Neelima; Cordonnier, Benoit; Boller, Elodie; Weiss, Jérôme; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Microscale heterogeneities influence failure mechanisms in the crust. To track the microstructural changes in rock samples when loaded until failure, we employed a novel experimental technique that couples dynamic X‐ray ...
  • Røyne, Anja; Bisschop, Jan; Dysthe, Dag Kristian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    [1] Subcritical cracking behavior and surface energies are important factors in geological processes, as they control time-dependent brittle processes and the long-term stability of rocks. In this paper, we present ...
  • Keszthelyi, Dániel; Dysthe, Dag Kristian; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Rocks under compressional stress conditions are subject to long‐term creep deformation. From first principles we develop a simple micromechanical model of creep in rocks under compressional stress that combines microscopic ...
  • Panahi, Hamed; Kobchenko, Maya; Meakin, Paul; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    During progressive burial, low permeability organic-rich shale rocks evolve chemically and physically as the temperature and stress increase and organic matter matures. The transformation of organic matter into hydrocarbon, ...
  • Pluymakers, Anne Marie Henriette; Liu, J.; Kohler, Felix; Renard, Francois; Dysthe, Dag Kristian (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    We present an experimental method to study time-dependent, CO2-induced, local topography changes in mm-sized composite samples, plus results showing heterogeneous swelling of coal and shale on the nano- to micrometer scale. ...
  • Panahi, Hamed; Kobchenko, Maya; Meakin, Paul; Dysthe, Dag Kristian; Renard, Francois (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The statistics and dynamics of fractures formed during the accelerated maturation of kerogen-rich shale was investigated by heating Green River Shale (R-8 unit, Piceance Basin, northwestern Colorado) core samples while 3D ...
