Abstract

To realize a life-time prediction of polymer specimen in case of fatigue load a fatigue model based on laboratory test has been introduced in this paper. This fatigue model provides an approximate description of the three life stage of polypropylene (PP) specimens. Using a stochastic module containing the probabilistic calculations of the fatigue model developed will serve for qualitative analysis.
