Deformation bands are the most common strain localization feature found in deformed
porous sandstones and sediments, including Quaternary deposits, soft gravity slides and …

A suite of true triaxial tests were performed on Castlegate sandstone to assess the influence
of the intermediate principal stress on mechanical response and failure. Five independent …

Deformation bands confined to a 9-m-thick layer of the Entrada Sandstone in Utah
accumulate less displacement per unit length than fractures that are not stratigraphically …

Deformation bands form in porous granular rocks by localized inelastic yielding that is well
described by a modified Cam cap model. All five kinematic varieties of bands observed in …

This paper presents a two-surface elastoplastic model for brittle–ductile transition behaviors
of porous rocks subjected to compressive stresses. Two plastic deformation mechanisms are …

Detailed observations of compaction bands exposed in the Aztec Sandstone of southeastern
Nevada indicate that these thin, tabular, bounded features of localized porosity loss initiated …

Strain localization in porous sandstones may significantly impact the regional fluid flow.
Previous laboratory studies that investigated permeability evolution with deformation …

Wiggly compaction bands in porous aeolian sandstone vary from chevron shape to wavy
shape to nearly straight. In some outcrops these variations occur along a single band. A …

Localized regions of deformation such as faults and shear zones are ubiquitous in the
Earth's lithosphere. However, we lack a simple unified framework of localization that is …

Grain crushing and pore collapse are the principal micromechanisms controlling the physics
of compaction bands in porous rocks. Several constitutive models have been previously …
