Web25 apr. 1991 · Jamming, Force Chains, and Fragile Matter ... Fragility is linked to the marginal stability of force chain networks within the material. It can lead to novel mechanical responses that may be relevant to (a) jammed colloids and (b) poured sand. The crossover from fragile to elastoplastic behavior is explored. Web15 iul. 2024 · One consequence of this is that some jammed states can exhibit fragility, as introduced by Cates et al. 2, where load-bearing force chains block the flow for the …

We argue that such media are generically … Web9 sept. 2003 · We have looked into an experiment that has been termed the "canonical example" of jamming: granular material, clogging the outlet of a container as it is discharged by gravity. We present quantitative data of such an experiment. ... Jamming, Force Chains, and Fragile Matter. Cates. Physical Review Letters, (9) 1998 Jamming of Granular …
Web19 dec. 2024 · Finally, in experiments of sheared frictional particles below \(\phi _{SJ}\), the stresses are mediated essentially along one-dimensional structures known as ‘force chains’. Such states are termed ‘fragile’ [5, 31], and are force balanced configurations with \(Z_G < d + 1\). We have not been able to capture the fragile states in our ... WebThe granular jamming transition is experimentally investigated in a two-dimensional system of frictional, bi-dispersed disks subject to quasi-static, uniaxial compression without vibrational disturbances (zero granular…
