Employing molecular dynamics simulations of two-dimensional soft particle packings, we investigate microscopic mechanical responses of granular materials to simple shear deforma-Tion. Though microscopic affine responses are deterministic, the restructuring of force-chain networks is well described by a stochastic method for the force distributions, i.e. a master equation. We find that microscopic responses of force-chains are anisotropic in average, while uctuations of forces are equiprobable in all directions, i.e. the probability of force uctuations is isotropic under simple shear deformation.
