Jee et al. assert (1) that the effect we measure— what happens to a lubricant film thickness in individual slip events during intermittent stick–slip sliding (2)—was already measured long ago (3, 4), and with better resolution. We are bemused by this assertion because in the works cited (3, 4) not only is intermittent stick–slip friction, with its characteristic saw-tooth pattern, not shown or ...

The mechanical behavior of saturated soil is mainly governed by the interaction between the soil skeleton and the pore fluid, and this interaction may lead to significant loss of strength known as liquefaction under seismic loading conditions. The main objective of this paper is to implement a cyclic constitutive model based on fuzzy set plasticity theory, which is capable of modeling soil dila...

We study the rheology of cornstarch suspensions, a non-Brownian particle system that exhibits shear thickening. From magnetic resonance imaging velocimetry and classical rheology it follows that as a function of the applied stress the suspension is first solid (yield stress), then liquid, and then solid again when it shear thickens. For the onset of thickening we find that the smaller the gap o...
