Nonlocal Granular Rheology: Role of Pressure and Anisotropy [PDF]
, 2013 We probe the secondary rheology of granular media, by imposing a main flow and immersing a vane-shaped probe into the slowly flowing granulate. The secondary rheology is then the relation between the exerted torque T and rotation rate \omega of our probe.

Rheology and Contact Lifetime Distribution in Dense Granular Flows [PDF]
, 2007 We study the rheology and distribution of interparticle contact lifetimes for gravity-driven, dense granular flows of non-cohesive particles down an inclined plane using large-scale, three dimensional, granular dynamics simulations. Rather than observing a large number of long-lived contacts as might be expected for dense flows, brief binary collisions

Ultraslow dynamics and stress relaxation in the aging of a soft glassy system [PDF]
Phys. Rev. Lett. 87, 245503 (2001), 2001 We use linear rheology and multispeckle dynamic light scattering (MDLS) to investigate the aging of a gel composed of multilamellar vesicles. Light scattering data indicate rearrangement of the gel through an unusual ultraslow ballistic motion. A dramatic slowdown of the dynamics with sample age $t_{w}$ is observed for both rheology and MDLS, the ...

Shear Banding from lattice kinetic models with competing interactions [PDF]
, 2010 Soft Glassy Materials, Non Linear Rheology, Lattice Kinetic models, frustrated phase separation} We present numerical simulations based on a Boltzmann kinetic model with competing interactions, aimed at characterizating the rheological properties of soft-glassy materials. The lattice kinetic model is shown to reproduce typical signatures of driven soft-

Dissipation and Rheology of Sheared Soft-Core Frictionless Disks [PDF]
Phys. Rev. Lett. 112, 208303 (2014), 2013 We use numerical simulations to investigate the effect of different dissipative models on the shearing rheology of massive soft-core frictionless disks in two dimensions. We show that the presence of Newtonian (overdamped) vs Bagnoldian (inertial) rheology is related to the formation of large connected clusters of disks, and that sharp transitions may ...

Herschel-Bulkley rheology from lattice kinetic theory of soft-glassy materials [PDF]
, 2010 We provide a clear evidence that a two species mesoscopic Lattice Boltzmann (LB) model with competing short-range attractive and mid-range repulsive interactions supports emergent Herschel-Bulkley (HB) rheology, i.e. a power-law dependence of the shear-stress as a function of the strain rate, beyond a given yield-stress threshold.

The rheology of direct and suspended extrusion bioprinting
APL Bioengineering, 2021 Bioprinting is a tool increasingly used in tissue engineering laboratories around the world. As an extension to classic tissue engineering, it enables high levels of control over the spatial deposition of cells, materials, and other factors.
