Abstract
We study here the dynamical behavior of disordered elastic systems such as gels or filled elastomers, by dissipative molecular dynamics. We show that applied macroscopic deformations result in non-affine deformations at the scale of the filler particles. These non-affine deformations lead to slow meso-scale reorganizations, which could explain the long relaxation times measured in gels, and also in rubbers even at temperatures much above the glass transition temperature.
