    Abstract

    The major field failure mode of high density polyethylene (HDPE) pipes is the brittle fracture caused by the quasi-static cracking. To determine the quick ranking on the resistance to the brittle fracture, the circular notched bar (CNB) specimen has been frequently used. The unique slow crack growth (SCG) feature of HDPE, the discontinuous SCG, are also observed in the CNB specimen. In this study, the discontinuous SCG of HDPE in a geometry of CNB specimen was predicted by expanding the current crack layer (CL) theory to the axisymmetric solids.
