Phase-field simulations of viscous fingering in shear-thinning fluids
Sebastien Nguyen, Roger Folch, Vijay K. Verma +2
A phase-field model for the Hele-Shaw flow of non-Newtonian fluids is developed. It extends a previous model for Newtonian fluids to a wide range of shear-dependent fluids. The mod…
Shaking-induced motility in suspensions of soft active particles
Denis Bartolo, Eric Lauga
We investigate theoretically the collective dynamics of soft active particles living in a viscous fluid. We focus on a minimal model for active but non-motile particles consisting…
Adhesive contact of elastomers: effective adhesion energy and creep function
Etienne Barthel, Christian Frétigny
For the adhesive contact of elastomers, we propose expressions to quantify the impact of viscoelastic response on effective adhesion energy as a function of contact edge velocity.…
Internal stress as a link between macroscale and mesoscale mechanics
Ken Sekimoto
The internal (or residual) stress is among the key notions to describe the state of the systems far from equilibrium. Such stress is invisible on the macroscopic scale where the sy…
