Web1 ian. 2015 · Jamming diagrams in a space of shear stress, τ, and packing fraction, ϕ. These diagrams pertain to T = 0 systems, which include granular materials. (a) is a sketch of the Liu–Nagel diagram [5], in which states at high enough ϕ and low enough τ exist in a jammed state, the darker region. (b) is the diagram that characterizes frictional ... Web18 feb. 2024 · The shear-jamming of dense suspensions can be strongly affected by molecular-scale interactions between particles, e.g. by chemically controlling their propensity for hydrogen bonding. However ...

WebAt the shear jamming point one finds well-defined packings, all characterised by their own set of critical parameters such as critical packing fraction, effective friction, etc. Packings composed of frictionless or almost frictionless particles are found to have a non-monotonic dependence of the macroscopic friction but a monotonic increase in ... 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 … Web7 nov. 2024 · Granular materials consist of macroscopic grains, interacting via contact forces, and unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, i.e. a transition between fluid-like and disordered solid-like states. Roughly twenty years ago, proposals by Cates et al for the shear response of colloidal systems and ... sfr business réunion
