Multiaxial fatigue behaviour of polypropylene pipes is investigated under tension and torsion loading with or without mean stress. Fatigue limit is experimentally determined and compared to self heating curve method. A multiaxial fatigue criterion is proposed and shows that the fatigue behaviour of this semi-crystalline polymer seems to be governed by the von Mises maximum stress. © 2010 Elsevier Ltd.
