Abstract Many polymers used in load-bearing applications show a range of fracture behaviour from ‘brittle’ to ‘ductile’ (see Ductile-Brittle Transition).All thermoplastics can show both kinds of behaviour, and unexpected tough-to-brittle transitions led to many service failures in the first few decades of their use. It is useful to distinguish three main regimes of brittle behaviour under relatively low stresses. Fatigue crack propagation is seen as a result of cyclic loading, slow crack growth is usually seen after long times under load at higher temperatures, and rapid crack propagation is usually seen as a result of rapid loading at lower temperatures.
