Notes:
The fatigue behavior of pure poly (vinylchloride) (PVC) and a PVC pipe compound has been investigated. Unnotched S-N lifetime, fatigue-crack growth, and craze/crack-initiation data are presented. The data trends, coupled with direct-microscopic observation, suggest that the unnotched-specimen lifetime in fatigue is dominated by the craze/crack-initiation process. This differs from the observed consistency of crack propagation and specimen-lifetime trends in several other polymers, whose failure can be traced to the initiation and growth to instability of a single dominant craze/crack.
