On the Fatigue Crack Growth Propagation in Rubbers
The study of fatigue crack propagation in elastomers is an essential prerequisite to improve the service of dynamically loaded rubber products such as tires or antivibrational components. However, the experimental method used to characterize the fatigue crack growth rate appears to be relatively unknown as compared to classical fatigue test methods. The aim of the present talk is thus to introduce this experimental method but also the different parameters influencing the crack growth behavior. We will particularly take a look at the specific behavior of natural rubber which exhibits a singular phenomenon named “strain-induced crystallization”, investigated here by the way of the Wide Angled X-ray Diffraction (WAXD) method.
