    Abstract

    To investigate the applicability of a theory developed by Schapery to crack growth in thermoplastic pipes, experiments were performed on high-density polyethylene (HDPE) pipes. In the experiments the pipes (with existing through-the-thickness cracks) were loaded by an internal pressure and the time-dependent crack length was measured. This was done at three different temperatures, 20, 30, and 80°C and for two cases of crack orientation, axial and circumferential. It was observed that the theory agreed reasonably well with the experimental data.
