Orientation dependent elastic stress concentration at tips of slender objects translating in viscoelastic fluids [PDF]
, 2019 Elastic stress concentration at tips of long slender objects moving in viscoelastic fluids has been observed in numerical simulations, but despite the prevalence of flagellated motion in complex fluids in many biological functions, the physics of stress ...

Interplay between viscosity and elasticity in freely expanding liquid sheets
, 2016 We investigate the dynamics of freely expanding liquid sheets prepared with fluids with different rheological properties, (i) viscous fluids with a zero-shear viscosity $\eta_0$ in the range $(1-1000) \, \mathrm{mPa.s}$ and (ii) viscoelastic Maxwell ...
