}(Received 6 September 2006 and in revised form 11 May 2007) This paper experimentally investigates the rheology of dense granular flow through its solid-like to fluid-like transition. Between the well-established flow regimes ‐ quasi-static and grain-inertial ‐ the physical description of the transition remains elusive. Our experiment uses a top-rotating torsional shear cell capable of ±1µm accuracy in height and 5 decades (10 "3 " 100rads "1 ) in rotation rate. The data on beach sand shows… CONTINUE READING
