We studied the mechanics of compactant failure in four sandstones associated with a broad
range of failure modes in the brittle‐ductile transition. While Berea and Bentheim …

We analyze the propagation of compaction bands in high porosity sandstones using a
constitutive model based on breakage mechanics theory. This analysis follows the work by …

To investigate how strain localization develops from a structural and stress heterogeneity,
we introduced a V‐shaped circumferential notch in cylindrical samples of Bentheim and …

Compaction bands are zones of localized grain crushing and porosity reduction, which form
spontaneously in high porosity rock under certain compressive stress conditions. Recent …

Porous rocks, subjected to compressive stress, often undergo mechanical compaction via
grain crushing and grain rearrangement, and chemical compaction by pressure solution …

Drilling experiments in rock blocks subjected to pre-existing true triaxial far-field stresses
simulating real in situ conditions often result in localized failure around the created borehole …

В работе предложены модификации моделей Друккера-Прагера-Николаевского и
Рудницкого и построены алгоритмы, необходимые для численного моделирования …

Drilling into rock blocks subjected to critical far-field stresses can result in localized failure
around the created borehole, manifested by the formation of two diametrically opposed …
