Abstract A hydro‐mechanical continuous model that accounts for volumetric internal erosion (otherwise called suffusion) is developed based on experimental observations and data to fill the gap between laboratory testing field applications. The proposed mixture theory applied a two‐phase four‐species porous medium. erodible soil partitioned in two phases: one solid phase fluid phase. composed of...

Cohesive granular media flowing down an inclined plane are studied by discrete element simulations. Previous work on cohesionless granular media demonstrated that within the steady flow regime where gravitational energy is balanced by dissipation arising from intergrain forces, the velocity profile in the flow direction scales with depth in a manner consistent with the predictions of Bagnold. H...

For a single soilbag filled with a cohesionless granular material analytical and numerical models based on a continuum approach are used to predict the evolution of deformation and stress under monotonic compression and plane strain conditions. Analytical models with different assumptions for the stress ratio distribution in the filling material, a constant volume and a frictionless interface b...

Meandering rivers are common on Earth and other planetary surfaces, yet the conditions necessary to maintain meandering channels are unclear. As a consequence, self-maintaining meandering channels with cutoffs have not been reproduced in the laboratory. Such experimental channels are needed to explore mechanisms controlling migration rate, sinuosity, floodplain formation, and planform morphodyn...

The numerical investigations of size effects in granular bodies during a quasi-static plane strain compression test are performed. To describe a mechanical behaviour of a cohesionless granular material during a monotonous deformation path in a plane strain compression test, a micro-polar hypoplastic constitutive model was used. It includes particle rotations, curvatures, non-symmetric stresses,...

In order to characterize the mechanical behavior of grain piles, we investigate the response of a noncohesive two-dimensional packing of cylinders submitted to a localized force. By means of image processing, we obtain an accurate measurement of the individual grain displacements in the reversible regime of deformation. The measured displacement field deviates unambiguously from the predictions...
