On the Stability of Dilatant Hardening for Saturated Rock Masses
Fissured rock masses tend to dilate as they are deformed inelastically toward failure. When the rock is fluid saturated and the time scale does not allow drainage, suctions are induced in the pore fluid, and by the effective stress principle the rock is dilatantly hardened over the resistance that it would show to a corresponding increment of drained deformation. This paper considers a compress...
متن کاملFluid dynamics of dilatant fluids.
A dense mixture of granules and liquid often shows a severe shear thickening and is called a dilatant fluid. We construct a fluid dynamics model for the dilatant fluid by introducing a phenomenological state variable for a local state of dispersed particles. With simple assumptions for an equation of the state variable, we demonstrate that the model can describe basic features of the dilatant f...
متن کاملShear Thickening Oscillation in a Dilatant Fluid
By introducing a state variable, we construct a phenomenological fluid dynamical model of a dilatant fluid, i.e., a dense mixture of fluid and granules that shows severe shear thickening. We demonstrate that the fluid shows shear thickening oscillation, namely, the fluid flow oscillates owning to the coupling between the fluid dynamics and the internal dynamics of state. We also demonstrate tha...
متن کاملElasticity of dilatant particle suspensions during flow.
Dense suspensions under sufficiently high shear stress can exhibit a dramatic transition to a solidlike state. This is known as extreme shear thickening and is sometimes accompanied by dilatancy. This behavior is contradictory; the material is solidlike but only when flowing. To probe the elasticity of the dilatant state, we measure the transient inertio-elastic oscillations that occur in respo...
متن کاملDiagenesis of Luxembourg Sandstone
Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...
