Multiaxial fatigue life predictors for rubbers: Application of recent developments to a carbon-filled SBR

• Exploring of multiaxial fatigue life predictors for rubbers.
• Best results found with stress and cracking energy-based approaches.
• Exploring of cumulative fatigue approaches.

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.
