“…Approaches that attempt to take into account the energy release rate of microscopic defects in order to render microscopic phenomena were previously investigated by Rivlin and Thomas (1953), Greensmith (1963), Lindley (1972), Young (1990) who related the tearing energy, i.e. the energy release rate of Griffith (1920) as applied to elastomers, to the strain energy density for classical fracture mechanics of rubber test specimens such as the single edge specimen or the trouser specimen.…”

International audienceFrom an engineering point of view, prediction of fatigue crack nucleation in automotive rubber parts is an essential prerequisite for the design of new components. We have derived a new predictor for fatigue crack nucleation in rubber. It is motivated by microscopic mechanisms induced by fatigue and developed in the framework of Configurational Mechanics. As the occurrence of macroscopic fatigue cracks is the consequence of the growth of pre-existing microscopic defects, the energy release rate of these flaws need to be quantified. It is shown that this microstructural evolution is governed by the smallest eigenvalue of the configurational (Eshelby) stress tensor. Indeed, this quantity appears to be a relevant multiaxial fatigue predictor under proportional loading conditions. Then, its generalization to non-proportional multiaxial fatigue problems is derived. Results show that the present predictor, which is related to the previously published predictors, is capable to unify multiaxial fatigue data

“…The plots of crack length a versus fatigue cycles N under strain of 50% and corresponding fatigue lifetimes are presented in Figure 6, as a typical example. 44 Considering that the fatigue tests were performed under constant strain, we also compared the fatigue resistance of composites under constant tearing energy. The fatigue lifetimes and crack growth rates of GO/NR composites under varied strains are shown in Figure 7 (a) and (b), respectively.…”

ARTICLE This journal isExfoliated graphene oxide (GO) reinforced natural rubber (NR) composites were prepared by a simple and promising latex co-coagulation method. Latex co-coagulation realized the complete exfoliation and uniform dispersion of GO in NR matrix. The quasi-static fracture and dynamic fatigue behaviors of composites were investigated. Mechanical properties and J-testing were used to characterize the fracture resistance, and fatigue tests were carried out under cyclic condition of constant strains. Results revealed that with increase in GO sheet content, the mechanical properties, fracture initiation and propagation resistance were all highly improved. A much higher reinforcing efficiency of GO sheets than that of traditional fillers was realized. Fatigue crack growth resistance was remarkably enhanced with the incorporation of only 1 phr GO sheets. The relatively weak fatigue resistance of composites filled with 3 phr and 5 phr GO was attributed to their high hysteresis loss and tearing energy input. It revealed that GO sheets would be promising filler in preparation of rubber composites with high fracture and fatigue resistance at low filler content.

“…The effects of carbon black properties on fatigue life (cycles to catastrophic failure) are illustrated in Table III [95]. In blends of certain elastomers, the cut growth rate can be minimized by an uneven distribution of carbon black between the two elastomers, favoring tear deviation [97]. High structure and small surface area are just the morphological features favoring good black dispersion (see Section V).…”
