EXPERIMENTAL DETERMINATION OF THE ELASTIC EQUILIBRIUM RESPONSE OF CARBON BLACK FILLED RUBBERS

ABSTRACT The experimental determination of the pure elastic response of filled rubbers remains a major challenge due to the very long times required for the viscoelastic effects to dissipate. Starting from an expedient proposed in 1930, we deal with an experimental procedure capable of dissipating viscoelastic effects in reasonably short times, to obtain a point-wise estimation of the intrinsic elastic response of the material.
