  • Critical Evolution of Damage Toward System-Size Failure in Crystalline Rock 
    Renard, Francois; Weiss, Jérôme; Mathiesen, Joachim; Ben-Zion, Yehuda; Kandula, Neelima; Cordonnier, Benoit (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Rock failure under shear loading conditions controls earthquake and faulting phenomena. We study the dynamics of microscale damage precursory to shear faulting in a quartz‐monzonite rock representative of crystalline rocks ...
  • Dynamics of microscale precursors during brittle compressive failure in Carrara marble 
    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 ...
  • Microscale characterization of rupture nucleation unravels precursors to faulting in rocks 
    Renard, Francois; Cordonnier, Benoit; Kobchenko, Maya; Kandula, Neelima; Weiss, Jérôme; Zhu, Wenlu (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Precursory signals, manifestations of microscale damage that precedes dynamic faulting, are key to earthquake forecasting and risk mitigation. Detections of precursors have primarily relied on measurements performed using ...
  • Synchrotron 4D X-Ray Imaging Reveals Strain Localization at the Onset of System-Size Failure in Porous Reservoir Rocks 
    Kandula, Neelima; McBeck, Jessica Ann; Cordonnier, Benoît; Weiss, Jérôme; Dysthe, Dag Kristian; Renard, François (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Abstract Understanding the mechanisms of strain localization leading to brittle failure in reservoir rocks can shed light on geomechanical processes such as porosity and permeability evolution during rock deformation, ...
