Web14 dec. 2011 · Jamming by shear. TL;DR: It is shown that jamming of frictional, disk-shaped grains can be induced by the application of shear stress at densities lower than the critical value, at which isotropic (shear-free) jamming occurs. Abstract: A broad class of disordered materials including foams, glassy molecular systems, colloids and granular ... load cell project using arduinoWebThe application of stress can drive a dense suspension into a regime of highly non-Newtonian response, characterized by discontinuous shear thickening (DST) and potentially shear jamming (SJ), due to the formation of a frictionally stabilized contact network.
