Stress transmission and isostatic states of non-rigid particulate systems
Raphael Blumenfeld
The isostaticity theory for stress transmission in macroscopic planar particulate assemblies is extended here to non-rigid particles. It is shown that, provided that the mean coord…
From Plasticity to a Renormalisation Group
R. C. Ball, R. Blumenfeld
The Marginally Rigid State is a candidate paradigm for what makes granular material a state of matter distinct from both liquid and solid. Coordination number is identified as a di…
Large fluctuations of disentaglement force and implications for polymer dynamics
Raphael Blumenfeld
This paper examines the effect of cooling on disentanglement forces in polymers and the implications for both single chain pullout and polymer dynamics. I derive the explicit depen…
Strange dynamics of domain walls and periodic stripes along classical antiferromagnetic chains
Raphael Blumenfeld
This paper addressses the kinetics and dynamics of a family of domain wall solutions along classical antiferromagnetic Heisenberg spin chains at low energies. The equation of motio…
The stress field in granular systems: Loop forces and potential formulation
RC Ball, R Blumenfeld
The transmission of stress through a marginally stable granular pile in two dimensions is exactly formulated in terms of a vector field of loop forces, and thence in terms of a sin…
