Article Preview

In order to understand the influence of gamma-irradiation, accelerated aging and Vitamin-E addition on the fatigue crack growth properties of UHMWPE, fatigue crack growth tests of UHMWPE plates using compact tension specimens were carried out. The specimen conditioned in -irradiation and accelerated aging (the -aging specimen) has faster fatigue crack growth rate than the virgin specimens. For the Vitamin-E added specimen (the VE specimen), however, K threshold of the -aging VE specimen is smaller than that of the VE specimen. This result shows that the addition of Vitamin-E reduced the decrease of K threshold by -irradiation and accelerated aging.
