    Faults in carbonate rocks show both seismic and aseismic deformation processes, leading to a wide range of slip velocities. We deformed two centimeter‐scale cores of Carrara marble at 25°C and imaged the nucleation and ...
  • 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 ...

    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 ...
  • McBeck, Jessica Ann; Kandula, Neelima; Aiken, John Mark; Cordonnier, Benoit; Renard, Francois (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Centuries of work have highlighted the importance of several characteristics on fracture propagation. However, the relative importance of each characteristic on the likelihood of propagation remains elusive. We rank this ...
  • 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 ...
  • Renard, Francois; McBeck, Jessica Ann; Kandula, Neelima; Cordonnier, Benoit; Meakin, Paul; Ben-Zion, Yehuda (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Understanding the approach to faulting in continental rocks is critical for identifying processes leading to fracturing in geomaterials and the preparation process of large earthquakes. In situ dynamic X-ray imaging and ...
