For evaluating the crack resistance of pipe grade polyethylene, several standard tests have been proposed but most industrial standards on crack resistance are not adequate for recently developed high performance pipe grade polyethylene due to extremely long time to test. Recently, a circular notched specimen (CNS) has been selected for studying the characteristics of the crack resistance of pipe grade polyethylene as a part of understanding quasi-brittle failure. CNS can create tri-axial stress status around the crack tip, so it can be good specimen geometry for developing an accelerated test. In this study, four types of pipe grade polyethylene were chosen and tested under variable fatigue loading conditions with various notch depths. The fatigue characteristics of four polyethylene were evaluated, and the fracture surface of CNS after failure is analyzed by optical microscope and scanning electron microscope (SEM) to evaluate the fracture mechanism of pipe grade polyethylene.
