We investigate experimentally the mechanical response to shear of a monolayer of bidisperse frictional grains across the jamming transition. We inflate an intruder inside the packing and use photoelasticity and tracking techniques to measure the induced shear strain and stresses at the grain scale. We quantify experimentally the constitutive relations for strain amplitudes as low as 10(-3) and ...

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...

We study the rheology of cornstarch suspensions, a non – Brownian particle system that exhibits discontinuous shear thickening. Using Magnetic Resonance Imaging (MRI), the local properties of the flow are obtained by the determination of local velocity profiles and concentrations in a Couette cell. For low rotational rates, we observe shear localization characteristic of yield stress fluids. Wh...

The macroscopic and mesolevel mechanical mechanisms of slip zone soil are a crucial subject for the research landslide deformation evolution slope control, but effects shape psephicity coarse particles in on properties still need to be explored. Discrete element method (DEM) can effectively monitor track parameters geotechnical materials, such as displacement vector field, contact force chain, ...

Titanium dioxide is widely used in numerous industries and with the newly developed titanium manufacturing technique, referred to as Near-net-shape Electrochemical Metallisation (NEM) Process, rapid precise production of components highly sought-after. This manuscript presents rheological investigation extrudability tests titania inks, establish improved via Direct Ink Writing. The indicated th...
