Abstract
Fatigue crack growth (FCG) experiments were performed on a commercial high density polyethylene (PE‐HD) pipe grade classified as PE 100 material. The effects of frequency on FCG behaviour were studied. Furthermore, FCG tests were interrupted in the region of stable crack propagation. The crack front and the front of the process zone ahead of the crack were systematically characterized via microscopic methods in the thickness direction of the specimen. The experimental data are employed to determine the effective crack length by compliance relationships.
