Abstract

Abstract: This work focuses on the characterization and the modeling of the complex dynamical behavior of a butadiene rubber filled with carbon black. This material is used in helicopter rotors and submitted to severe operating conditions. In particular the effects of the environmental temperature, of the amplitudes and frequencies of cyclic loading are studied. A new constitutive model that takes into account the Payne effect, the frequency, temperature and pre-loading dependencies is proposed. A specific material parameter fitting strategy is also introduced.
