Shear reversal in dense suspensions: the challenge to fabric evolution models from simulation data [software]

Rahul Chacko, Romain Mari, Suzanne Fielding & Michael Cates
Dense suspensions of hard particles are important as industrial or environmental materials (e.g. fresh concrete, food, paint or mud). To date, most constitutive models developed to describe them are, explicitly or effectively, โ€˜fabric evolution modelsโ€™ based on: (i) a stress rule connecting the macroscopic stress to a second-rank microstructural fabric tensor ๐™Œ ; and (ii) a closed time-evolution equation for ๐™Œ . In dense suspensions, most of the stress comes from short-ranged pairwise steric or...
