Paper Abstract

Several studies have been conducted that involved full scale investigation of rapid crack propagation (RCP) in polyethylene (PE) pipes. Greig & Ewing showed that the critical pressure in a plastic pipe, which governs RCP, is very sensitive to temperature and that stringent controls on operating and proof test pressures are required for large diameter PE pipes. Leevers and Yayla demonstrated with the S4 (Small Scale Steady State) test excellent correlation with the full scale test on smaller diameter pipes. Vanspeybroeck changed the S4 into the S5 (Small Scale Steady State Scum) test to avoid any decompression in the pipe sample and to simulate full scale testing. In this paper, we present some preliminary results of testing aided by holographic interferometry to determine stress fields associated with RCP.
