  • Description: Polypropylene (PP), without and with fillers and reinforcements, is widespreadly used in applications where a high resistance to repeated loading, i.e. to fatigue, is required. The fatigue performance can be characterized either by the endurance limit (the maximum allowed stress causing no damage after 106 fatigue cycles) or by the description of the fatigue crack propagation (FCP). The latter approach, based on the fracture mechanics, is straightforward when the PP material is inhomogeneous, i.e. when inherent flaws of various origin and type are present. Such flaws may act as initial cracks and grow under the prevailing external loading conditions. In that case, the life expectation of the material or construction part is determined by the FCP behavior. On the other hand, if the controlling step is the development of cracks or more generally damage, the target is to determine the fatigue endurance limit and describe the related curve (i.e. maximum stress versus cycle number, S-N; Wöhler curve). From the viewpoint of the loading mode, a distinction is generally made between static and cyclic (sometimes falsely termed dynamic) loading.
