Transients in shear thickening suspensions: When hydrodynamics matters
Shear-thickening suspensions can be brought to shear jamming: under constant volume flow at finite stress is impossible. If the volume is not fixed and the suspension can dilate, what are the stress levels in the suspension? We show that Darcy flow couples to dilation to give stresses scaling as the square of the size over which dilation occurs. This result is quantitatively modelled using a Reynolds-like dilatancy law and the Wyart-Cates constitutive model, which can e.g. shed light on the stresses observed during impact on shear-thickening suspensions.
