Water Saturation Induced Strength Degradation of Callovo-Oxfordian Claystoneuction activities of underground radioactive waste repositories can induce a desaturation and a resaturation process of the hosted rock. The present work is devoted to an experimental characterization of the water induced strength degradation the COx argillite under constant strain rate loadings. Ar

Emergence of Strain Localization in Porous Rocks Characterized by Full-Field Measurement in Plane Stying the emergence of strain localisation in rock specimens. Two porous rocks have been investigated, a sandstone and a clayey rock. Both show similarities in the strain localization process, with an early diffuse strain localization pattern well before the stress peak that evolves progressively tow

Localization in Plane Strain Compression of Fluid-Saturated Rockr undrained. This phenomenon is evaluated in plane strain compression experiments with water-saturated Berea sandstone, where corresponding poroelastic and inelastic properties were measured. Non-uniformity of lateral deformation and clustering of acoustic emission events were used as the experiment

3D Particle-Scale Displacement Gradient to Uncover the Onset of Shear Bands in Sandaxial compression test. Individual sand particles were identified and tracked through multiple strain increments. The paper presents the concept of displacement gradient to expose the inception of shear bands (strain localization) in sheared sand. Each particle’s neighboring particles were identifie

Periodic Stick-Slip Deformation of Granular Material Under Quasi-static Conditionscro-scale. Analysing the data base collected during a series of small scale model tests the evidence was found of periodic deformation mode, induced within the granular material by a series of very small displacement increments. Image analysis was used to study the phenomenon. It was found that ther

Modeling Physico-Chemical Degradation of Mechanical Properties to Assess Resilience of Geomaterialsion induced by non-mechanical processes and variables. That includes: hydro-thermal fracture, thermal collapse, chemical mass removal or accretion (dissolution or precipitation), chemical shrinkage/swelling, drying shrinkage, capillary force evolution during pore water phase change. The properties a
