Query: Stress controlled rheology of dense suspensions using transient flows   Dense suspensions of hard particles in a Newtonian liquid can be jammed by
shear when the applied stress exceeds a certain threshold. However, this
jamming transition from a fluid into a solidified state cannot be probed with
conventional steady-state rheology because the stress distribution inside the
material cannot be controlled with sufficient precision. Here we introduce and
validate a method that overcomes this obstacle. Rapidly propagating shear
fronts are generated and used to establish well-controlled local stress
conditions that sweep across the material. Exploiting such transient flows, we
are able to track how a dense suspension approaches its shear jammed state
dynamically, and can quantitatively map out the onset stress for solidification
in a state diagram.
