Abstract

The mechanisms of failure of externally notched sections of polyethylene pipe under pressure have been investigated. Previous communications had suggested that the origins of branching fracture features could be localized shear deformation and this is confirmed. It is shown that craze-like forms which occur at the crack tip can have a different structure to that of a craze.
