ABSTRACT
Furthermore, new parts developments tend to show that the swaging will increase more and more due to need of better lifetime.
1.2 Accounting for reinforcement phenomena in lifetime prediction
Late after the pioneer work of (Cadwell, 1940) (Fig. 2), some authors have tried to plot this kind of Haigh diagram for their own materials in order to model it for lifetime prediction (André et al., 1997), (Saintier et al., 2006), (Robisson 2000),
1 INTRODUCTION
1.1 Industrial motivation
In the automotive industry, anti-vibration parts designed with natural rubber undergo complex fatigue loadings. They are characterized by a positive minimum value for highly calibrated multi links bushes. As a consequence, a so called reinforcement phenomenon usually related to strain induced crystallization increases the lifetime compared to non calibrated parts. An example of these bushes and the related Road Load Data (RLD) are illustrated on Figure 1.
