Abstract

We present here an innovative identificatfion strategy, using high power ultrasonic loadings together with both InfraRed Thermography and Ultra-High-Speed Imaging, able to fully-characterize the viscoelastic behaviour of polymer materials from a single sample. The main originality lies in the fact that contrary to conventional DMT Analysis, no frequency or temperature sweep is required since the experiment is designed to simultaneously produce both a heterogeneous strain-rate state and an heterogeneous temperature state allowing a local and multi-parametric identification.
