Internal Reorganization of Agglomerates as an Explanation of Energy Dissipation at Very Low Strain for Heterogeneous Polymer Systems

Résumé

The addition of a new mechanism to the Leonov model is described to capture the energy dissipation observed for highly filled systems even at very low strain values. By considering that flocs can undergo deformation before rupture, an internal reorganization within the agglomerates is introduced as a dissipative mechanism. The present improved model describes both oscillatory and strain sweep experimental results with only one additional, physically meaningful parameter: the number of hopping particles in the flocs which may be obtained from microscopic observations. Consistent values of this number are found in agreement with the histograms of the particle dispersion.
