Failure mechanics of uPVC cyclically pressurized water pipelines

Joseph, S.H. / Leevers, P.S.

An extensive investigation has been directed towards explaining fatigue failure of pressurized water pipelines under serviceconditions, in terms of laboratory studies of the base material (unplasticized polyvinyl chloride, uPVC). It is established that many such failures are located in the regime to which linear elastic fracture mechanics can be applied, with encouraging predictive accuracy.Only failures at very low stress levels are not reliably explained by these methods, which nevertheless provide direction for further study.
