AC electrical properties as a sensor of the microstructural evolution in nanocomposite materials: experiment and simulation

This work deals with the AC electrical properties measurements under large strain of composites strongly contrasted in the viewpoint of their electrical and mechanical properties. First, the possibility to model a strongly heterogeneous material (from the viewpoint of electrical properties) using an improvement of a RC-type model is explored; this model relates the R and C values to the geometrical characteristics of the network of reinforcing …
