摘要

A simple "viscoplastic" model has been used here to model a filled SBR vulcanizate; the objective is to predict dynamic properties, in particular the Fletcher-Gent or Payne effect, from non-cyclic stress-strain data. A simple fitting procedure is described to obtain the parameters of the viscoplastic model from the stress relaxation data and stress-strain loading curves at constant rate. Special attention is given to keeping the numbers of parameters and of characterisation tests small. Elastic models are incapable of representing several aspects of the material behavior whereas it is confirmed that the proposed "viscoplastic" approach captures the essence of the behavior.
