scope:

The occurrence of brittle failures in welded structures has inspired many investigations of the notch toughness of steels, and as a result of this work in any different laboratory tests for evaluating notch toughness have been proposed. It is naturally desirable to establish the degree of correlation among results of the different tests, and to assess the significance of test results in terms of service behavior. These issues are discussed in the light of an extensive Literature search and experimental investigations.
