| Abstract: | 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.
