Effective viscoelastic behavior of short fibers composites using virtual DMA experiments

Résumé

May it be for environmental or economic reasons, mass reduction has become one of the main goals in mechanics. The short fiber thermoplastics composite is an interesting possibility since it presents a good compromise between a relatively easy process and mechanical properties. The aim of this work is to estimate and model the viscoelastic behavior at small strain of PC Lexan/Glass fiber composites. To meet this goal, a full field homogenization method based on solving the boundary problem through FFT is used. Virtual DMA experiments are used to build the master curve of the composite. They are later used to identify a macroscopic model for transverse isotropic short fiber composites. Finally, a meta-model is built to estimate the behavior of the composite at any given fiber volume ratio.
