Abstract

1. Analytical relations were established which make it possible to determine the temperature Tb for standardized specimens. 2. It was shown that it is possible to use either of the known relations of(T) or KIc(T) and the value of ΔTb to find the other relation-say KIc(T). 3. The analytical expressions obtained in the present study for Tb agree qualitatively with the changes seen in practice in the quantity Tb under the influence of radiation due to a change in loading rate, variation of the geometry of the specimen and CSM, variation of the notch radius, or other factors.
