In this paper, localized deformation in partially saturated sand was investigated
quantitatively using microfocus X-ray computed tomography (CT) and an image analysis of …

Geoscientists are confronted with the challenge of assessing nonlinear phenomena that
result from multiphysics coupling across multiple scales from the quantum level to the scale …

We present a multiscale investigation on the initiation and development of compaction
bands in high-porosity sandstones based on an innovative hierarchical multiscale approach …

Ductile deformation is ubiquitously found in the shrinkage of geomaterials. The existence of
ductility requires elastoplastic mechanics when analyzing the structure deformation under …

Faults play a major role in many economically and environmentally important geological
systems, ranging from impermeable seals in petroleum reservoirs to fluid pathways in ore …

Numerical simulators have become indispensable in geomechanics to model increasingly
more complex rock behaviours by harnessing the growing computational power available …

We present a study on compaction band in a high-porosity limestone (Tuffeau de Maastricht)
based on comparison and analysis of X-ray tomography observations and computational …

We study the mechanical failure of cemented granular materials (eg, sandstones) using a
constitutive model based on breakage mechanics for grain crushing and damage …

The formation of compaction bands in porous brittle rocks such as sandstones and
carbonates has a significant impact on the localization mechanisms preceding earth and …

Cnoidal waves are nonlinear and exact periodic stationary waves, well known in the shallow
water theory of fluid mechanics. In this study we retrieve such periodic stationary wave …
