Towards constitutive equation for non-linear mechanics of PDMS-nanosilica

Résumé

Nanosilica reinforced PDMS is a performing material, but with a complex mechanical response. In our project we aim at modelling its behavior through a multi-scale approach. This paper presents the main advancements in the development of a mechanical constitutive equation from a microscopic physical law. Experimental results prove the modification of the polymer chain dynamics. Mobility reduction is reproduced by gradients in the viscoelastic properties of confined matrix. A wide spectrum of relaxation times allows the representation of a large span of different behaviors by means of one single function.
