Jamming by shear
Web15 dec. 2011 · A minimum shear stress is needed to create robust, shear-jammed states with a strong force network percolating in all directions. … WebThe 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. Investigating how the molecular weight of the sus

Web6 iul. 2024 · Shear jamming, a relatively new type of phase transition from discontinuous shear thickening into a solid-like state driven by shear in dense suspensions, has been shown to originate from frictional interactions between particles. However, not all dense suspensions shear jam. Dense fumed silica colloidal systems have wide applications in … Web5 mar. 2024 · Jamming can occur in frictional granular materials undergoing shear at a fixed packing fraction, $$\\phi $$, within a range below the isotropic jamming point, with the amount of strain required to induce jamming, $$\\gamma $$, increasing with decreasing $$\\phi $$. We are interested in how the shear jamming process is affected when the …
