摘要：

This paper presents a comparative analysis of crack propagation in high density polyethylene (HDPE) under fatigue and creep loading conditions. This analysis is focused on the issue of mechanistic similarity between creep and fatigue failure in this material. Demonstration of such similarity is a crucial step in establishing the validity of fatigue as an accelerated laboratory test for long-term field failure under creep conditions. The Crack Layer approach is utilized as the analytical tool of the present investigation. It is demonstrated that, within the limits of the current analysis, mechanistic similarity with creep failure is preserved when fatigue is used as an accelerating agent for HDPE crack propagation. © 1990.
