Abstract
The fatigue properties of a series of vinyl urethane polymers have been examined by determining the crack propagation rates as a function of the applied stress intensity factor. Measurements were also made of the craze lengths at the tips of the fatigue cracks, and the craze stress and crack opening displacement calculated. A model for fatigue-crack propagation based on cumulative damage within the crazed material has been proposed which is consistent with the observed results.
