“…Actually, the out-of-phase multiaxial loading presents tongues with rounder morphology. On the other hand, lower fatigue life has been reached with the highest tongues density, which is consistent with the results of Poisson et al [19].…”

“…Poisson et al [20] have pointed out the caracteristics of macroscopic fatigue failure surfaces corresponding to multiaxial fatigue damage, with a fatigue zone and an end of life region. Poisson et al [19] have pointed out the importance of the fatigue zone in tension fatigue damaging, and a possible relationship between the « tongues » density and the fatigue lives. Therefore, a focus has been opted for the fatigue zone.…”

“…They distinguished two different features of the fatigue damage : the striations and the tearing. Poisson et al [19] have observed tongues in the fatigue initiation zone of the material. They have highlighted a possible relationship between fatigue damage and the tongues for tension -tension fatigue.…”

Some fundamental studies carried in a synthetic rubber - Chloroprene CR29 are presented in the first part of the paper. A critical analysis of test results, shows that an energy based approach permits the determination of fatigue lives in this material. This aspect is further enhanced by biaxial fatigue tests in the same material. These tests covering a life range from 10000 to 1000000 cycles show that the energy based model is very efficient to describe the fatigue behavior. Some evidence of strain induced crystallization (previously observed in natural rubber) with associated life enhancement at high load ratios is also presented. A comprehensive model based on the determination of the constitutive laws taking into account the viscoelastic behavior is developed showing excellent correlation with experimental data.
