Abstract

The effects of processing of unplasticized polyvinyl chloride (uPVC) pipes on fatigue-crack growth in terms of mean stress, frequency and fatigue-crack initiation, as well as on creep rupture, were investigated. No significant processing effect was observed on fatigue crack growth rates and fatigue crack initiation. However, creep rupture with three-point bending tests was significantly affected by the processing level. Two orders of magnitude difference in time to failure were found between well and poorly processed pipes caused by the large difference in the stress intensity factor at fracture instability between these pipes.
