Zur bruchmechanischen Untersuchung von Reaktorgraphit

Fracture mechanics is a well established tool for the assessment of brittle fracture in metallic structural materials. In this paper an attempt is made to apply fracture mechanics to a reactor-grade graphite. The effect of several test parameters on the stress intensity factor was measured; this was found to lie in the range 25 and 50 N/mm$^{-3/2}$. The results are discussed in terms of the well known mechanical characteristics of graphite
