Journal of Fluid Mechanics 465 (2002): , … WebMay 12, 2024 · We show a new trend of dense granular flow behavior above average normal stress of 0.3 MPa with weakening at high strain rate, which may be explained by shear-thinning thixotropy. Experimental results for a given shear rate at normal stresses between 0.3 and 1 MPa show a bifurcation in shear-resistance behavior. The trend of all …
