Pre‐conditioning is usually not considered in classical lifetime prediction analyses. The strong material softening observed in rubber materials, however, makes one expect a strong influence of the pre‐conditioning on the lifetime. For this contribution, experimental tests were carried out to verify and further investigate, how the pre‐loading affects the lifetime of filled natural rubber. Comparing the experimental results with according simulations using the MOdel of Rubber PHenomenology (MORPH) [1, 2] it is found that even though the simulation shows an extended lifetime with higher pre‐straining, the experimental data shows no significant influence of this pre‐conditioning.
