Abstract
Repeated tension tests on centre-notched sheet specimens show that the rate of growth of fatigue cracks in polymethylmethacrylate is constant if the range of crack-tip stress-intensity factor is constant. Within the limits considered fatigue-crack growth rate was independent of specimen thickness and loading history.Keywords
