抄録

In this paper, rotating-bending fatigue tests for polyetheretherketone (PEEK) were carried out to investigate the fatigue characteristics of plain and notched specimens at room temperature. The results were discussed using linear notch mechanics. In the case of the plain specimen, fracture always occurs from defects and the crack growth rate is very high. The fatigue crack initiation of this material is of the point-initiation type and the fatigue strangth is very sensitive to a notch. The fatigue strength of an arbitrarily notched specimen of this material will be estimated from the present results rearranged based on linear notch mechanics.
