This precis is aimed as a practical field-guide to situations in which shearbanding might be expected in complex fluids subject to an applied shear flow.Separately for several of the most common flow protocols, it summarises thecharacteristic signatures in the measured bulk rheological signals that suggestthe presence of banding in the underlying flow field. It does so both for asteady applied shear flow, and for the time-dependent protocols of shearstartup, step stress, finite strain ramp, and large amplitude oscillatoryshear. An important message is that banding might arise rather widely in flowswith a strong enough time-dependence, even in fluids that do not supportbanding in a steadily applied shear flow. This suggests caution in comparingexperimental data with theoretical calculations that assume a homogeneous shearflow. In a brief postlude, we also summarise criteria in similar spirit for theonset of necking in extensional filament stretching.
