The results demonstrate three regions in the creep curves: (i) In the initial viscoelastic region, the chainlike (at ϕ = 0.05) or percolated three-dimensional network (at ϕ = 0.30 ) structures fill up the gap and the average cluster size remains constant (ii) Above a critical strain of 0.1 (10%), in the retardation region, these structures begin to break and rearrange under shear. Experimental and simulation data are in good qualitative agreement. Simulations are mostly started with random initial structures with some additional tests of using preassembled single chains in the low concentration case. m −1) in order to match the yield stresses developed in both systems for easier comparison.Two particle concentrations are investigated ( ϕ = 0.05 and 0.30) at two different magnetic field strengths (53 and 173 kA A direct comparative study on the creep-recovery behavior of conventional magnetorheological (MR) fluids is carried out using magnetorheometry and particle-level simulations.
