At higher tearing energy, beside other factors affecting the FCG performance of the RRP compounds, both higher absolute and relative hysteresis loss are slightly detrimental to the crack growth rates.
The non-linear correlation between the properties indicates that factors such as SIC plays an important role at specific dynamic strain amplitudes and could partially delay the crack growth rates of the rubber compounds.
