Motion of fluorescent tracer particles when suspension is imaged 50 μm inside (σ = 2,000 Pa, ϕ = 0.57). Before 3.56 s and after 93.6 s, there is no applied stress. Total elapsed time is 100 s, and average γ˙ = 27.3 s−1. Localized stress fluctuations drive shear thickening in dense suspensions Vikram Rathee, Daniel L. Blair, and Jeffrey S.
