Average storage and loss bulk moduli in the solid and fluid phase for disordered tilings.
(a,c) Average storage (B′) and loss (B″) bulk moduli as functions of the deformation frequency, ω0, for different values of the cell-shape parameter, p0, (a) deep in the solid phase and (c) deep in the fluid phase. The error bars represent the standard error of the mean. (b,d) The collapse of the moduli curves for different values of p0 for (b) the solid phase and (d) the fluid phase. The insets show the representation of the Standard Linear Solid (SLS) model in terms of the springs and dashpots. (e) Average storage (B′) and loss (B″) bulk moduli as functions of the deformation frequency, ω0, for intermediate values of the cell-shape parameter, p0. (f) The collapse of the moduli curves for for intermediate values of the cell-shape parameter, p0. Dashed curves in (a,c,e) are the fits based on the SLS model [see Eq (5)].
