Influence of mean stress and mean strain on fatigue life of carbon black filled natural rubber

Résumé

The recent determination of end of life criteria for multiaxial loads enables to design new parts undergoing relaxing solicitations. The application of these criteria for non-relaxing solicitations, which represent more adequately the loads applied on antivibration parts on service, is still an unanswered matter. Previous studies carried out on test specimen highlight an increase on duration life when minimum solicitation is higher than a threshold level: this phenomenon is known as reinforcement. Parameters namely test control, load ratio and level of maximal solicitation were identified to be relevant to reinforcement penomenon. In order to investigate their influence over duration life, an experimental campaign was performed. For each test condition, the mechanical threshold level where from which reinforcement appears is clearly identified. A single reinforcement law, suitable for propagation and initiation tests, is established.
