Fatigue crack growth (FCG) experiments were conducted on two high density polyethylene (PE-HD) pipe grades with various test specimen configurations such as compact type (CT) and circumferentially notched bars (CNB). The effects of R-ratio and frequency on the FCG behavior were studied. While FCG rates showed a great dependence on R-ratio in terms of stress intensity factor range, the effects of frequency may be considered significant in the low crack growth region. These experimental data were employed for lifetime prediction based on the crack layer theory.
