Temperature impact on the mechanical and fatigue behavior of a non-crystallizing rubber

Jacopo Schieppati et al.

Summary: Temperature has a significant impact on the mechanical and fatigue behavior of carbon filled acrylonitrile butadiene rubber (NBR). Tensile tests and Mooney-Rivlin plots revealed a decrease in ultimate properties and maximum chain extensibility with increasing temperature. Dynamic moduli showed an Arrhenius dependence above a certain temperature, and fatigue resistance decreased at higher temperatures.

Influence of the tensile static preload dependency on the dynamic lifetime prediction for an HNBR elastomer

H. El Maanaoui et al.

Summary: The study proposed a correlated lifetime prediction concept for load cases without static preload, analyzing crack growth and particle size distribution, and found that the predicted values were in reasonable concordance with experimental findings.
