Motion of fluorescent tracer particles near the bottom of the suspension (σ = 1,000 Pa, ϕ = 0.56). Before 3.86 s and after 94 s, there is no applied stress. Total elapsed time is 100 s, and average γ˙ = 25.4 s−1. Localized stress fluctuations drive shear thickening in dense suspensions Vikram Rathee, Daniel L. Blair, and Jeffrey S.
