Abstract

The purpose of this study is to give an insight on the existing fatigue criteria for rubbers and their capability to predict the fatigue life of a carbon-filled styrene–butadiene rubber (SBR) under constant and variable amplitude tests. Strain, stress and energy-based predictors are compiled using combinations of tension and torsion tests. Stress and cracking energy-based predictors are found to have the best prediction capability for constant amplitude tests. Variable amplitude tests highlight the nonlinear nature of the damage by fatigue of the SBR material. A comparison between several cumulative laws is provided.
