To validate the proposed model, a series of combined pressure deflection tests conducted on 110-mm SDR 11 PE 2 (AUS) pipe.
However, it is noted that while crazing evidence was observed in each of the pressure deflection tests, ultimate failure occurred by yielding and drawing of remaining material ahead of the notch.
The pressure deflection curve is measured using the setup in Figure 4 for a circular deflection area.
