Composite materials are being used in the design of new devices to produce more
functional, cheap and on-demand products. In particular, 3D printing technology based on …

Piezoelectric materials are usually characterized using resonant methods. However,
piezoelectric polymers are used in broadband devices, thus requiring characterization over …

The present work presents a model to evaluate the average inclusion strain in the matrix of a
bulk polymer. The new model considers a two-phase polymer (matrix and inclusions), where …

This work describes the dielectric properties of piezoelectric poly (vinylidene fluoride)(PVDF)
thin films in the frequency and temperature ranges relevant for usual applications. We …

This work presents a study of the structural changes in aged EPDM (ethylene-propylene-
diene monomer) from outdoor high voltage transmission lines. Samples were taken from …

A model for studying the mechanical internal stresses into dielectric materials is developed
in the present work. The model takes into account the formalism of inclusions in continuous …

In the present work, a study on the dependence of the Dielectric Strength (DS) as a function
of the empty space and the internal stresses into polymer samples has been performed. The …

An electrorheological model is applied to results from dynamic mechanical analysis in order
to relate low-frequency dielectric properties to viscoelastic response. The model describes …

An electro-rheological model based in Voigt units which takes into consideration the
variation in volume promoted by electrostriction is developed. The model was based on a …

We have studied the problem of the change in volume in a dielectric material due to the
deformation process promoted by the application of an alternating electric field. The …
