A Viscoelastic-Viscoplastic Characterization with Time Temperature Superposition for Polymer Under Large Strain Rates

Abstract : In the sectors of activity such as the automotive industry, polymers are definitively present into the different components of the vehicle. These materials may be subjected to high loads such as crash impact. Therefore, they have to meet strong requirements in terms of safety regulations. It is so important to know and to anticipate the behavior of the material in a wide strain rate and temperature range in order to predict the risk of failure. In this paper, some results of experimental research are proposed about the dependence between the strain rate and the temperature for viscoelastic and viscoplastic behavior in the perspective to build an efficient experimental procedure of behavior characterization. The studied material is a 15 wt% mineral (talc) filled and impact modified copolymer propylene ethylene.
