- Abstract:
- The fatigue behavior of different thermoplastic polyurethanes is discussed and compared to a cross-linked thermoset H-NBR elastomer. The characterization of the fatigue behavior is of great interest for long-term properties under cyclic loading. There is hardly any fatigue data available for these new classes of materials. There are two common ways to describe the lifetime of an elastomer fatigue behavior. One method is the classic fatigue test to generate the Wöhler curve. The other approach is focused on fatigue crack growth using the Tearing Energy or J-Integral concept. Displacement controlled cyclic test were performed and local strain based Wöhler curves were determined in this paper.
