  • Crack tip fields during crack growth by cutting and by fatigue have been computed via finite element analysis for experiments executed on the Coesfeld Intrinsic Strength Analyser. The results show that cutting with a sharp blade produces a much reduced dissipative process zone in front of the crack tip, in comparison with the process zone produced by fatigue at nominally similar conditions. Because the energy released by a growing crack supplies both the process of breaking polymer chains to form crack faces, and the dissipative process at the crack tip, it is concluded that minimizing the magnitude of the crack tip dissipation causes the observed remaining energy release rate during a cutting experiment to approach the limit reflecting the breakage of polymer chains. In this way, a relatively brief cutting experiment can be used as an indicator of long-term fatigue behavior.
