The solid–fluid transition in a yield stress shear thinning physical gel (2009, background): “As proposed by Derec and coworkers (Derec et al. 2003) in the case of silica suspensions and previously observed experimentally by Coussot and coworkers in the case of pastes ( Coussot and Tabuteau 2006 ), after all transient effects disappear (t > tt), the dynamic elastic modulus varies logarithmic”
Yielding to Stress: Recent Developments in Viscoplastic Fluid Mechanics (2014, methodology): “This has been observed with materials similar to those analyzed by Barnes (1999), such as Carbopol gels (Coussot et al. 2006, Divoux et al. 2011, Moller et al. 2009), muds (Coussot et al. 2002a, 2006), and mayonnaise (Caton & Baravian 2008, Da Cruz et al. 2002).”
Yield stress fluid flows: A review of experimental data (2014, background): “It seems that the rheological properties of yield stress fluids in the solid regime vary as widely as for usual solids, ranging from almost purely linear elasticity (for concentrated emulsions) [14-15] to complex elastoplasticity for cement paste [16] through non-linear viscoelasticity for Carbopol ”
Mapping thixo-elasto-visco-plastic behavior (2017, methodology): “The type of deformation (e.g., shear or extension) and the controlled amplitude must be specified. a Experimental data from nonlinear creep compliance (step shear stress) of a thixotropic yield stress fluid (bentonite suspension, adapted from Coussot et al. (2006), their Figs.”
Yield stress and elastic modulus of suspensions of noncolloidal particles in yield stress fluids (2008, background): “This last property can also be measured through the slump test [Pashias et al. (1996); Roussel and Coussot (2005)], or through creep tests [Coussot et al. (2006)]: if a creep stress above the yield stress is imposed then the material flows steadily whereas for a creep stress below the yield stress…”
Effect of Coarse Particle Volume Fraction on the Yield Stress and Thixotropy of Cementitious Materials (2008, methodology): “These problems imply that we cannot preshear our materials with the rheometer and that we cannot use a yield stress measurement method based on a shear flow such as shear rate [8] or shear stress ramps [44] and creep tests [45]; we then have to measure the static yield stress.”
